Hello, My name isXXXXX you for choosing Just Answer, It is my pleasure to assist you today. is it just the fan that pops the breaker when you turn it on ?
No the exhaust fan works fine when used by itself. It's trying to start a microwaving session that pops it, making me think the accumulation of grease on the fan inside is causing resistance to starting the microwaving session.
But it's the microwave itself that is tripping, not our houses electrical circuit?
Are you suggesting putting in a 25 amp, or a 20 amp if the house one is a15 amp, so it takes that surge? We did have all new ELS several years ago and new wiring in the new kitchen.
But what I am not getting is why the microwave's breaker is popping and not our house breaker panel? Forgive me, I am not an electrician.
Yes, The microwaving unit just stops after a few seconds of pushing the command. This does not happen every time however. We'll get several normal uses, then a stop. We restart by unplugging and then plugging in again and resetting the command. Sometimes it takes several resets to fiinally get a complete cook cycle to run through. My wife said she thought it was popping only on short warm ups like 30-60 seconds, but we've had it pop at jsut about any setting it seems?? We haven't tried to see what happens at a range various times settings.??
Okay. If the unit will reset, even after unplugging it a few times then it is not blowing the internal fuse. What you have is an intermittent failure of the main control circuitry, or possibly the magnetron itself.
If it was a gunked up fan causing this it would be blowing the internal fuse or popping the breaker at the houses electrical panel. If the internal fuse blows the unit will not operate until it is replaced.
The control board does have an internal reset that will kill the power to the unit if there is an overload of the system. Unfortunately without diagnosing the problem there is no way to tell you which component is going out.
I am sorry but this is going to require hands on testing by a repair person.
Let me know if you need anything else.
Just one more question then. If as you say "an internal reset that will kill the power to the unit if there is an overload of the system", is there some chance that if I cleaned the greased up interior/fan, how would I do that?
Gottcha, I was there when they installed it and both guys were sweating! Think I'll try setting a range of cook times and see if there's any pattern to where the popping happens. Appreciate at least having you to kick this around with. Useful service and well worth $30 to at least eliminate what it isn't caused by! Ill leave this open and get back after I try that.
Thanks, XXXXX XXXXX
