Tripping GFI Coffee spilled in the bottom of the microwave and tripped the GFI. I took the unit apart and cleaned up the mess. The system will run on a direct circuit and I get the clock on the microwave. After about 1 minute of just the clock, the GFI circuit trips again. Haven't even tried to power it up on the GFI circuit...clearly there is a problem. Any suggestions would be appreciated before the kids get home! Thanks

Hi,

If the unit quit working while cooking then your not in a good situation. There are 3 fuses/cut off thermostats inside the unit that if they break when in use--means something else caused them to break and you have another problem.

You will have to pull the unit completely down and then take off the outer case of the unit to look inside. The most common fuse that breaks is located just behind the control panel and it's a 1" long ceramic cylinder fuse. If it has no continuity then get another and see what happens when you start the cycle.

I should warn you that microwaves are the one appliance not recommended for do-it-yourselfers because they store a charge in the capacitor and if not handled correctly and you touch the wrong wire it can actually KILL you.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

If the key pad not working, then there can be many causesfor this behavior (or lack of behavior): 1. Door is notclosed - on many ovens; there will be no response to any buttons - even settingthe clock - unless the door is securely closed. 2. You waited toolong - some models (like Sharp) have a timeout. If you close the door but don'tproceed to activate any functions with a couple of minutes, they will requireyou to open and close the door to reset their pathetic brains. 3. Controller isconfused - a power surge or random non-reproducible action of the universe mayhave resulted in the controller's program ending up in an infinite loop. Pullthe plug for a minute or two to reset it. 4. Defectiveinterlock switches - this can result in the controller thinking the door isopen and ignoring you. 5. Faulty controlleror its power supply - a power surge may have damaged the electronics. Otherthan checking for bad connections and obviously bad power supply components,diagnosing this will be tough without a schematic (and possibly much more). 6. Touch pad orcontroller board contaminated by overenthusiastic cleaning - if you recentlypower washed the oven (or even if you only use some spray cleaner), some mayhave gotten inside and shorted out the touch pad or controller. 7. Defective ordamage touch pad - physical abuse is not a recommended technique for getting amicrowave oven to cooperate. If there is any visible damage to the touch pad -the outer film is broken - it will probably need to be replaced. Also Spillsare a common cause of keypad problems, so if the keypad is not working it isimportant to check for residue that could indicate a spill. If a spill issuspected, simply cleaning the keypad thoroughly and allowing it to dry may fixteh problem. It may take a couple of days for the keypad to dry thoroughlyafter a spill has been cleaned up, so it is important to be patient. If display is totally dead: 1. Ifall functions work normally including heating but the display is blank(assuming you can issue them without being able to see the display), theproblem is almost certainly in the controller or its power supply. 2. Trypulling the plug for a minute or two - for some reason the display portion ofthe controller may have been sent out to lunch by a power surge or alphaparticle. It wouldn't be the first time. 3. Checkfor bad connections between the display panel and the power supply and solderjoints on the controller board. 4. With everything else operational, a bad micro controller chip is not that likely but is still a possibility. If the ovenwas physically abused, the display panel may have fractured though it wouldtake quite a bit of violence. In this case, more serious damage to the doorseals may have resulted as well which would be a definite hazard. To check the main fuse: 1. Unplug the oven and locate and remove the main fuse. Itwill usually be a 1" x 1-1/4" ABC ceramic type directly in-line withthe Hot (black wire) of the power cords. 2. If it is blown, suspect problems with the interlockswitches, high voltage capacitor, or high voltage wiring. 3. If it is good but the oven makes a loud humming soundwhen you attempt to cook, suspect the magnetron or high voltage diode. Hope this will help you. Good Luck.
