In Houston, people sometimes take our appliances for granted– especially our microwaves– until they break down. Even the popular Houston Amana microwaves can malfunction without warning and get homeowners to look for help fast.
Before things get worse, you can look for signs of microwave trouble. According to an article on SFGate.com, a microwave that heats slowly or not at all means it is failing due to a faulty tube in the appliance’s high-voltage system. Other signs to look out for are loud noises such as bangs, knocking, and rattles while the microwave is operational.
Just like any other appliance, you should first unplug the microwave before troubleshooting. Additionally, you have to discharge the microwave’s capacitor lest you get the (electric) shock of your life. You then attach a wire to the two ends of the resistor, the other wire to the screwdriver, and the other end to the capacitor terminals.
Next, you should look at the microwave one part at a time. For starters, you check the power cord for signs of damage or burn marks. If you do not find anything there, you then open the protective shell of the microwave and check its other parts. More specifically, you should check if the door switch deteriorated, if the fan motor quit working, or if the fuse is blown.
