Most common repairs needed to fix a Maytag microwave
Thermostat Replacement
A bad thermostat in a microwave will cause a variety of issues, mainly with power to the components of the microwave. Microwaves have several internal thermostats that protect you from harm when components inside the microwave fail. Many microwaves have a magnetron thermostat that trips when it detects high current going to the magnetron or high temperature in that area of the microwave cavity. Another thermostat monitors the temperature of the cooking cavity and trips when high temperatures occur. If any of these thermostats trip, the microwave won’t start, lights and fans will be inoperative and the display will be blank. Because microwaves contain a high-voltage transformer and high-voltage capacitors that retain a lethal amount of electricity even with the microwave unplugged, a Sears Home Services professional should examine the microwave and perform the repair.
Electronic Control Board Replacement
If a microwave electronic control board is malfunctioning, it can lead to various failures in the microwave, including a lack of power or heating, or it could prevent the microwave from turning off. This is because the board serves as the brain of the microwave, controlling crucial components such as magnetron the heats food, cooling fans, lights, the turn-table motor, cooking times and power level settings and the display. If the electronic control board malfunctions, it can disrupt communication between many different components. A failing board may cause a chattering or clicking noise or emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.
Switch Replacement
A broken switch in a microwave will cause a variety of issues, mainly with power to the components of the microwave. Microwaves have several internal thermal switches and interlock switches that protect you when components inside the microwave fail. Door interlock switches prevent the microwave from running when the door is open so you aren’t exposed to harmful radiation. Many microwaves have a magnetron thermal switch that trips when it detects high current going to the magnetron or high temperature in that area of the microwave cavity. Another thermal switch monitors the temperature of the cooking cavity and trips when high temperatures occur. If any of these switches fail, the microwave won’t start, lights and fans will be inoperative and the display will be blank. Because microwaves contain a high-voltage transformer and high-voltage capacitors that retain a lethal amount of electricity even with the microwave unplugged, a Sears Home Services professional should examine the microwave and perform the repair.
What to expect when you experience a Maytag microwave no heat issue
How is the no heat problem fixed?
Correcting most no heat problems usually involves replacing the thermostat, electronic control board or switch. However, there are many potential causes, so a thorough diagnosis is key to fixing the problem. An accurate diagnosis is essential to understanding how much the repair will be.
Sears Home Services recommendations for a microwave that won't heat
When the microwave has no heat it can be for many reasons. To avoid replacing unneeded parts, we recommend scheduling Maytag repair near you with one of our local Sears Home Services professionals. The technician can perform diagnostic tests to identify the root cause of the problem and fix it for you. Our technicians are experienced at diagnosing all types of microwave failures.
What to look out for with a microwave no heat diagnosis
Diagnosing modern appliances without proper knowledge and training can be difficult. Without using proper diagnostic techniques, fixing your microwave problem will only be achieved through changing parts on a hunch. Appliances, especially in the last 10 years, have become extremely advanced, and many models have electronic parts that are difficult to test. DIY repairs on the latest appliance models are becoming increasingly difficult.
Maytag Microwave Will Not Heat
When your Maytag microwave will not heat, follow these troubleshooting steps:
- Check that the microwave door is fully shut. A Maytag microwave will not heat unless you properly shut the door. Make sure the microwave door is firmly shut before attempting starting the appliance.
- Remove the shipping spacer from a brand new Maytag microwave. If your microwave is brand new, be sure to remove the shipping spacer along with any residual packaging that may be preventing the latch from engaging the door.
- Disable the Control Lock. If you see Loc or L in the microwave display, unlock the controls by pressing and holding the STOP/CLEAR button for 5 deliberate seconds. The routine for disabling the Control Lock feature on your Maytag microwave may differ. Follow the procedure described in your owner’s manual if you’re unable to disable the Control Lock feature using the STOP/CLEAR button.
- Reset the electronic control board. Resetting the electronic control board can sometimes resolve an internal logic problem. Unplug the microwave power cord for 5 minutes and then plug it back in. The control board will reboot and may start working properly so the microwave will heat.
If these basic troubleshooting tips don’t help you resolve the problem when your Maytag microwave will not heat, schedule microwave repair service and we’ll send a Sears Home Services technician to your home to fix the issue.
