Alex June 26, 2015 for Model Number GMH6185XVS3 Everything works except it won't heat on any level, any help please.
1 Answer Hello Alex. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the transformer should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. All of these are +- 10%. If all the readings are proper and in range, replace the magnetron. Read More...
Roger June 20, 2015 for Model Number Microwave Maytag Model # MMV6180WS-1 My microwave suddenly quit working. No current. Check the circuit breaker and reset several times but still doesn't work. What went wrong and how can I fix it? Thanks for any answer. Roger
1 Answer Roger, You will want to check the fuse to make sure that it has continuity. If there is no continuity the you will need to replace the fuse. Also check the door switches to make sure that they are good. Read More...
Dan May 11, 2015 for Model Number dont have it My roper over the range microwave is 8 years old everything works eccept the cooking of the food. Could it be the fuse and where is it located?

Christie May 06, 2015 for Model Number MH2175XSB5 Need to change the fuse. Where is it located? Found it on the schematic but still not sure what I have to do to replace it. Thanks
1 Answer Christie, The fuse is located behind where the control panel is. You will want to remove the air grill and then remove the single screw where the control is and lift the control panel off this will give access to the fuse to be able to remove and replace it. Read More...
1 Answer Wendell, To access the thermal fuse you will need to unplug the unit and take the air grill and control panel off. The fuse should be visible at this point. It may be on just a clip or on a control board that you can pop the fuse out and install a new one. If the fuse blew then it is likely that there is another part failure. The most common would be a faulty door switch causing the fuse to blow. Read More...
Larry C. March 26, 2015 for Model Number WMH31017AS0 My microwave just stop working. Took it apart to find that the bottom switch the button at top seems to press in very freely. Where as the top switch presses in like it has a spring and makes a clicking noise . Unlike the bottom switch does you think this switch could be my problem. Are do you think i have other problems .Switch part #ap4429884
1 Answer Larry, Based on the description of the problem, yes the switch if it is not clicking and springing back up then the switch is bad but you will also want to test the ceramic fuse to make sure that the fuse has not blown. Test for continuity and if there is not continuity then the fuse is bad. Read More...
Waterdogdad January 02, 2015 for Model Number MH2175XSQ0 I replaced the stove top light bulb but it still does not work. All other aspects of the Whirlpool microwave are functioning. What might be wrong? Thanks
1 Answer Hello Waterdogdad, This can be a bad light socket 8206374, a harness issue W10107710, or a bad control board 8206619. I'm sorry but the "lamp housing" or socket, has been discontinued by the manufacturer and no satisfactory substitutions have been provided. Read More...

Speedy July 01, 2014 for Model Number maytag mmv4203d05 Hi bought this a few years ago and never installed it until a couple days ago it seems that everything seems ok until I treid to warm something but nothing happens. It's still cold. What could it be?
