    Oven Repair in Nairobi & Mombasa

    1. The Gas Burner Won’t Light If you have a gas stove, you can light the range burners with a match if the electric ignition isn’t working. However, if the burners won’t light, and it’s not the result of an obvious problem like a power outage, you should troubleshoot it.

    Lift off the burner grate, burner cap and burner base. Clean any food debris out of the burner with a toothpick or some compressed air. Clean the grate, cap and case while you’re at it. Check the wires connecting the igniter to the control module. If there’s a loose connection here, tighten it. Burner still won’t light? You may need to replace the igniter. There could also be another problem, like a kink in the gas line. Time to call the pros.

    2. The Range Burner Won’t Heat If you have an electric stove, your range burners need electricity in order to heat up. Sometimes, these burners go bad and need to be replaced. If one of your electric burners won’t heat up, follow these steps:

    Switch out the faulty burner with one that you know works. Simply unplug it from the burner socket and plug the working one in. If the working burner heats up, the problem is your burner. Replace it. If the working burner doesn’t heat up, the problem is either the infinite switch or the socket. Does the socket look burned or damaged? You may need to replace it. Test the burner again. If it still doesn’t work, test and replace the infinite switch. issue with oven temperature

    3. The Oven Won’t Heat An oven that won’t heat is usually the result of a faulty igniter (for a gas oven) or heating element (for an electric oven). If both your gas oven and your gas burners have stopped working, the problem is most likely with the gas line, and will require professional repair. However, you may be able to replace the heating element or igniter yourself.

    Use a screwdriver to remove the old igniter or heating element. Heating elements are usually located inside the oven, while you can access an igniter from underneath. To get to your igniter, remove the broiler or storage drawer. Make sure to turn off the power to your oven before servicing it. If your heating element is of the hidden variety, you may need to call a repairman to replace it for you. 4. The Oven Won’t Heat to the Right Temperature This could be a problem with the temperature sensor, the gas igniter or the heating element.

    Check the temperature sensor. It shouldn’t be touching the inside wall of the oven. Use an ohmmeter to make sure the sensor is functional. The resistance should rise as the temperature of the oven increases. If the sensor isn’t working, replace it. Verify that the heating element or gas igniter is working, and replace it if not. If everything’s been checked or replaced, recalibrate the oven. Heat the oven to 350 degrees Fahrenheit. Check the temperature inside the oven with an oven thermometer after 20 minutes, and every 20 minutes thereafter for the next 90 minutes to two hours. Add up the sum of the temperature readings, and divide by the number of readings you took, to get the average temperature of the oven. Adjust the oven’s temperature dial accordingly. 5. The Oven Door Won’t Shut An oven that won’t shut isn’t safe for use. Follow these steps to fix it:

    Unplug the oven and turn off the gas, if it’s a gas model. Pull straight up and out on the door to remove it from the oven. If it won’t pull up, look to unscrew any screws holding the hinges in place inside the oven. Check the hinges. Replace them if necessary. Check for broken door springs. Slide out the bottom drawer and look under the oven to see the door springs. Remove any broken springs with pliers. The ends should be wrapped around two bolts. Replace them, rewrapping the ends of the new springs around the bolts. Replace the silicone or rubber gasket around the door. If the oven door still won’t shut, the door sensor may need to be replaced. Related: Appliance repair near you

    Just like other light bulbs, the one inside your oven occasionally goes out. Here’s how to replace it:

    Remove the bulb cover, usually by giving it a quarter-turn counterclockwise. Remove the old bulb by pulling it straight out. Using a dry cloth or gloves to handle the new bulb, replace the old bulb with one of the same type. 7. The Oven Won’t Self-Clean What good is a self-cleaning oven that won’t self-clean? Here’s what to do if your self-cleaning cycle stops working:

    Make sure you’re starting the cycle correctly. Set timers and knobs correctly. Manage your expectations. Large spills inside the oven will leave a layer of ash that may still require some manual cleaning. If you’re still having trouble with the self-cleaning cycle, you’ll probably need to call a repairman to replace the door lock motor and switch, control board, thermostat or some other component that is keeping your oven from running the self-cleaning cycle.

    If the electric oven that you use to cook your meals has stopped working, there are a number of possible reasons why. So you know you need to make some electric oven repairs, but which?

    Most of the things that often go wrong with electric ovens are relatively easy to fix, so don’t start worrying about how you’re going to afford a new cooker just yet – first, have a read of this guide to common electric oven repairs and see if you might be able to correct the issue yourself.

    SAFETY FIRST! Before attempting any electric oven repairs, be sure to switch off and unplug the appliance. Never work on an electrical appliance that is still connected to the mains. If in doubt, don’t risk damaging your oven and/or harming yourself – call in a professional.

    Oven element Problem: The oven is not heating up because the element (the bit that actually gets hot when you switch the oven on) isn’t working.

    Solution: This electric oven repair is fairly common, to fix it order a new oven element for your appliance and use this to replace the faulty element.

    How to replace oven heating elements >

    Thermostat Problem: Your oven’s thermostat – which measures the heat inside the oven and switches off the element once the desired temperate has been reached – is not working properly. As a result, your oven is not getting hot enough, getting too hot, or failing to heat up at all.

    Solution: Purchase a replacement thermostat for your electric oven and replace the one that isn’t working.

    Oven maintenance refers to all the procedures and activities (covered by a program for plant maintenance) carried out to preserve the initial operating conditions (mechanical, thermal, and electrical) of an oven and and its parts.

    Oven Maintenance

    Oven maintenance activities should focus on the following aspects:

    Scheduled inspection of the oven’s overall status
    Replacement of loose/flaking, worn, rusty, damaged, or broken components (e.g., nuts, screws, bolts, screw threads, taper pins/fasteners)
    Regular lubrication of moving parts and/or metal-to metal contacts (drives, motors, bearings, chains)
    Repair and welding of equipment subject to stress and load
    Oven maintenance is essential to guarantee its ideal conditions of operation and conservation. A properly maintained oven:

    Offers a longer service life to the baker
    Guarantees maximum equipment availability
    Works efficiently in terms of fuel consumption to directly bake the products
    Generates minimum heat losses (e.g., through the humid air extraction system and wall insulation)
    Ensures steady state conditions during baking, hence producing consistent quality
    Prevents breakdowns, idling, and rework
    Minimizes explosion risks (e.g., in the case of direct gas-fired ovens)
    Reduces downtime and prevents total plant shutdowns that directly affect production, order deliveries, and sales
    Relevance
    Oven maintenance is a key component of the whole plant maintenance program. Members of staff (e.g., in purchasing, maintenance, quality, and operations departments) should pay special attention to the oven because it:

    Imparts final and definite characteristics to the products
    Is the equipment with the longest cycle time in the production line
    Is the processing unit that consumes the majority of the energy (fuel and electricity) used by the plant
    Is the machine with the highest acquisition costs (lease/rental prices, depreciation and amortisation costs, value of asset, commissioning, and setup charges)
    Greatly affects the total manufacturing costs of a bakery, according to its energy efficiency
    Broken and/or malfunctioning ovens can bring bread-making plants to a standstill. Medium-sized and retail bakeries usually operate under the “we fix it” approach, in which the maintenance department performs all maintenance activities and interventions. These activities are “firefighting” maintenance that occurs when one of the ovens, mixers, or proofers in the processing line breaks down.

    In the traditional bakery, the production department works under the “we operate the oven and run it until it breaks” mentality. Oven operators generally do not perform any maintenance activities. Instead, the operators contact the maintenance department when the oven breaks down. In addition, the operators are inactive during the maintenance activities.1

    When the production line is operating smoothly, a down or broken piece of equipment impacts all preceding steps (i.e., mixing of ingredients, dough make-up operations, and proofing), thus increasing the risk of product contamination and deterioration.

    This is why bakeries should migrate to a proactive maintenance approach for ovens, which covers:

    Preventive maintenance: Planned sequence of inspections, interventions, and repairs designed to avoid equipment failure.
    Corrective maintenance: Scheduled interventions or works for malfunctioning or broken equipment in order to restore it to proper working condition.
    Unscheduled maintenance: Reactive interventions or works immediately performed when a critical repair and/or replacement is needed, often during unpredicted breakdowns.
    Temporary repairs: Quick repairs that use a variety of approved temporary materials (e.g., tape, wire, strings, cardboard, plastic) and that are replaced with permanent repairs as soon as possible.2
    How it works3
    In order to execute and sustain oven maintenance activities, bakeries require management guidelines, operating procedures, safety instructions, oven maintenance manuals from the manufacturer, trained and educated personnel, documentation, and recordkeeping.

    The following equipment parts and conditions should be taken into account in the oven maintenance subprogram:

    Welded metal components
    Driving chains and belts
    Motors and drives
    Steam lines and fittings
    Air lines and fittings
    Seals and gaskets
    Fans/blowers
    Fan filters
    Explosion door arrangement
    Oven flues
    Bearings
    Conveyor belts/bands
    Oven band tension
    Automatic tracking rollers
    Temperature controllers
    Sensors
    Motors and electrical control equipment
    Dampers
    Burners and gas equipment
    Oven maintenance checklist4
    Different types of ovens require special attention. A preventive oven maintenance subprogram, including adherence to the manufacturers’ recommendations, should be established and followed. This program should set a minimum maintenance schedule that includes inspection and work interventions. An adequate supply of spare parts should be maintained, and inoperable equipment should be cleaned, repaired, or replaced, as required.
