Solving common microwave issues can be simple with the right tools and knowledge. Anyone can tackle one of the most prevalent problems with microwaves using a screwdriver, step stool, star driver, and a replacement microwave door switch. This appliance is crucial, serving as the go-to appliance for countless families. So what exactly is this common issue with microwaves?
Fixing a Simple Microwave Problem
The common problem with most damaged microwaves involves a broken door switch. It leads to the disposal of many otherwise functional appliances. If a microwave is starting, turning the turntable, and displaying the countdown but failing to produce heat, that is a clear indication that the door switch has to be replaced. So, how do you do it?
Turning off the power is the first step. The microwave needs to be unplugged, and the upper plastic vent covering the screws has to be removed. Standing on a step stool, remove the head screws above the door and lift the vent away. If the plastic vent isn’t blocking the screw holding the control panel, skip this step.
Disassembling the Microwave
To disassemble the microwave, begin by unscrewing the top-right head screw on the control panel and lifting it back. Photograph the wire connections for reference. Pinch and detach the wire connectors, allowing the control panel to hang by the green wire. Optionally, remove the control panel backing by undoing the screws and disconnecting the wires.
The next step is removing the faulty door switch. Unscrew the star screw, release the door switch housing with a flat-blade screwdriver, and pry the old door switch from its housing. Remove the two wires.
Assemble Everything Carefully
Now, it is time to install the new door switch. Attach the wires, align the plastic pins, push down until it clicks, and tighten the star screw. For microwaves with a plastic backing, reattach it and add screws. Reattach the control panel by securing all wires, pushing it against the frame, and reinstalling the head screw. If needed, reinstall the left-side plastic vent.
Restore power by plugging in the microwave. Enter the current time and press start to reset the display. The final step is testing the microwave by heating water for a minute. In over 90% of cases, this resolves the issue. You should seek professional help for bigger repairs if this doesn’t fix the problem.
