Probably a short inside the microwave circuitry.  I had a Daewoo and had nothing but trouble with it.  Main board went out in a year, then again in another year.  Finally went to Home Depot where I bought it and was told that they had nothing but trouble with them and quit selling them.  Now I have a GE Spacemaker.

Started tripping the GFI outlet. Outley appears to functioning correctly after re-set, but the microwave keeps tripping it when I plug it back in


HI Joe
Couple of things to consider here.
  1. There may be a GFI plug there at the microwave, but it can get tripped by current leakage on other parts of the circuit. If there are other things plugged into the circuit (every outlet that's on the same panel breaker), it's possible any of them could be causing the tripping. Unplug anything else on the circuit, then plug things back in one by one to see if there's something that may make it pop.
  2. The reset switch in a GFI plug is mechanical. If it's been tripped a few times, it may be worn or not fully reset. Electrical guides usually suggest testing / resetting GFI plugs monthly, both to make sure they work, and also to cycle the mechanical switch. If dust, toaster crumbs, or other stuff might have gotten into the mechanism, it might not be mechanically resetting properly. Try test/reset/test/reset a few times and see if any of the clicks start feeling more distinct.
  3. The trip can be legit. Hopefully not the microwave, but if there is a short in the line somewhere, you really want to track it down before it causes a fire. In some cases, even heavy dust on/in outlets can cause pseudo-shorts with some current trickling to ground. GFI switches will usually trigger with less than 5 mA of current drop, so it doesn't take much. Blow out the receptacle with canned air.
The switch or it's connections may be bad. Unplug the microwave and (no cutting corners here), turn off the breaker to the plug. Undo the faceplate and mounting screws and pull the plug away from the wall. Check that the wire connections to the plug are tight, and that the wire nuts connecting the plug to the wall lines are also firm and tight. Tighten if necessary. If you're still getting trouble after trying this all, Consider replacing the outlet and seeing if that helps.

Hoping this helps!

Microwave clock and panel was lit in am wasn't used but in evening when went to use it isn't lit and won't work at all


Hello Anonymous

At the risk of starting with the very basics, when you say that the clock and panel aren't lit and wont' work at all, the first place to look is the wall power. You may be missing power from the wall because:
  1. The microwave isn't plugged in. Someone may have yanked a plug to plug in a mixer, phone charger, thanksgiving animated ornament, or what have you. Trace the cord back and make sure it's plugged in.
  2. Make sure the outlet has power. Take some plug-in-able item and plug to the outlet and see if it can turn on. If not:
  1. A number of kitchen outlets may have GFI switches, especially if they are anywhere near sinks. The GFI may have been tripped. There should be a reset switch in the middle of the plug. See if it's tripped, and reset if necessary.
  2. The breaker may have been tripped. Most kitchen circuits are wired to 20Amp breakers. If this is elsewhere in the house, like in an entertainment room or such, it is likely a 15 Amp outlet. Microwaves can draw a fair amount of power. Someone using another kitchen appliance, hair dryer, or what have you, on the same circuit, may have tripped the breaker. Newer code may specify an AFI or GFI breaker for kitchen outlets. In that case, a fault with something else on the circuit may have tripped the breaker. If that is the case, and it trips again, talk to an electrician. You don't want a fault like that undiagnosed.

    3) You may also want to try plugging the microwave into another outlet, even if the normal outlet seems OK

    If there's wall power and a good plug-in, then you work back to the microwave itself. A number will have fuses. Also, there may be interlocks that kick in if, for instance, the carousel rotation is impeded - that can mean something on the carousel is hitting a wall, which can risk tipping something over and spilling, or risk mucking up the reduction gears for the carousel axle if it keeps pushing.

    At that point, looking for specifics on your microwave model will be needed. You may also try the Microsoft Support approach - i.e unplug it for 5 minutes, then plug it back in and see if it works.

    Hoping this helps, Good Luck!

Coffee spilled microwave while heating now microwave is dead it is a general spacemaker what can I do


Wow, generally a spill in a microwave shouldn't be catastrophic, but if it blew the wall plug, something bad happened. What do you mean it blew the plug? Did it simply trip a GFI? a breaker? Either way something must be amiss inside. Best case is a blown fuse in the microwave. You can look inside for evidence of a short but follow all safety practices and ensure the unit is depowered and steer clear of the big capacitor as it could still be charged.

Hello

Plug the microwave into the outlet if the microwave won't power up. Make sure the plugs on the microwave match the type of outlet. A four-pronged outlet can only be used with a four-pronged plug. Same with three-pronged outlets---they only work with three-pronged plugs.


Inspect the plug. Make sure it hasn't been cut or tampered with. Four-pronged plugs can't be cut down to fit a three-pronged outlet. Three-pronged plugs mustn't be forced into four-pronged outlets. A three-pronged plug mustn't be used in a two-pronged outlet, either.


Replace blown fuses, or if there's a circuit breaker, check it for tripped breakers. Sometimes the trip won't be obvious, so cycle the circuit breakers. Turn them all the way off and then back on again.


Plug another appliance in the outlet. You will find this easier with three-pronged appliances. Simply plug a toaster, or other appliance into the microwave's outlet, and see if it works. If it works, you know the problem is with the microwave, not the power circuit. Have the microwave serviced or replace it. If the toaster or other appliance doesn't turn on, you know the problem is with the circuit.
