FixyaSOLVED: Microwave fan won't turn on.
The microwave oven is one of the most used appliances in modern homes.Microwaves are quick to encounter glitch thanks to continual usage.General Electric microwaves are known for their reliability, but they are not immune to issues in the microwave oven.
If the oven's filters are not clean, a GE microwave fan/vent could have problems.A malfunctioning thermostat or fan motor could be the reason.The control board of the oven may need to be replaced.
A microwave oven is a complicated machine and can encounter a lot of issues.The three major concerns relating to GE microwave exhaust fans have been looked at in detail.If you have a GE microwave and are currently facing issues with the machine's fans, you want to be prepared for future issues.
A host of things could have gone wrong if the GE microwave oven fan was not working.The filters, exhaust fan motor, thermostat, control board, etc. could be at fault.The main control board is less likely to fail than the fan motor and thermostat.You can't rule out the possibilities.
Check the air filters.The air filters in microwaves help absorb pollutants and odors from the food being heated.Over time, the contaminants can build up and cause obstructions.A metal or charcoal mesh filter can be washed.If it is dirty, replace it.
The grease filter of your microwave is similar to the air filter.The grease filter helps keep the exhaust system clean by trapping oils and fats from food being heated.
The bottom of the oven is where the filter is located.To clean the filter, take it out.Water and soap can be used to clean the filter.There are signs to look for when cleaning the grease filter.You may have to buy a new filter if the dust and dirtAccumulation is very stubborn.
It is possible to inspect the filters and make it right again.Clean the oven frequently.
The GE microwave has a damper that prevents air from outside from entering the oven.A flap made of plastic or metal is used to open the exhaust conduit when the fan is running.The flap could be designed to open and close with gravity.
If you suspect foul play by the damper assembly, inspect for items that may be preventing the component from opening and closing.Look for signs of cracking, wear, or damage in the damper.Look for a replacement damper if there are any issues.
If the cleaning methods don't work, disassemble the oven and clean the components individually.During this stage, broken parts will come to light.
Take the exhaust fan motor out and turn it on.The motor should be replaced if the blades don't move.
If the blades turn, test the fan motor for power and continuity using a multimeter.The fan motor should be replaced if it still doesn't work.If the motor doesn't have continuity, a replacement is on the way.
A faulty main control board could be to blame for the exhaust fan motor not doing its job.More on the board and its vulnerabilities later.
The fan on your microwave can be turned on when you need it.The exhaust fan won't work if the thermostat has issues.
Check if the thermostat has continuity.Repairing the thermostat won't be practical or worth your time, so look for another thermostat.
It is a rare occurrence for the main control boards to go bad.Control boards are often misdiagnosed.After checking the fan motor, wires, and various other components, the board must be looked into.You may call out the board if the exhaust fan doesn't work because it's not clear why.
There is a chance that the exhaust fan of the GE microwave is malfunctioning.The exhaust fan is turned on by the thermostat.The fan is no longer under control when the thermostat doesn't sense heat.
The main control board could turn on the fan with no input from the user.This could be due to a loose user interface connection or a cold solder joint.
Check the status of all connections if the control panel is the problem.Remove the ribbon-like cable from the mainboard if the connections are good and then clean the board.
If there is an issue after the cleaning, put everything back together.The problem should no longer be there if the board is fine.Look for a replacement board if the problem continues.
The integrated exhaust fan won't turn on if the microwave thermostat has problems.The fan motor could be to blame.
If the microwave thermostat does not conduct continuity, it will fail.If there is no continuity, replace the thermostat.There is no standard thermostat for GE microwave ovens.Look for a compatible thermostat and check your microwave model.
A microwave oven could be storing a lot of electricity even when it is not being used.Even if your oven is not connected to power, it could still shock you.It is recommended that you don't handle the equipment yourself or treat the repair as a do-it-yourself project due to the electric shock possibility.
If you have professional experience handling and repairing microwave ovens, you should be able to work on the appliance.Do not attempt to repair or replace the board.You can hire a licensed technician.
A licensed technician is needed for most microwave repair work.
The main control board of your microwave rarely goes bad.The thermostat is more prone to failure.The exhaust fan can run longer and harder in certain microwave oven models due to the thermostat being super-sensitive.
Replacing the thermostat is not a hassle because it is inexpensive.Getting to the thermostat can be a problem.It's not uncommon for the oven to be completely uninstallable to access the component.Contact an experienced technician if you don't know much about microwave ovens.
