The loud pop was almost certainly the high voltage diode going bad. To find parts, I suggest you call the number on your owner's manual or check with the store where you bought it. Sunbeam may not make this part available, so be prepared. Maybe they have authorized servicers in your area. Ask them about that. Good luck.

No Light and the turntable is not working

Open your microwave completely unscrewed but make sure it is disconnected from the power; check all the other fuses inside, if it doesn't fix the issue then take it to a pro to get this fix.

There is an internal fuse but if you still have power on the display then likely the main transformer has failed and the cost to repair will likely exceed a replacement.

Less than 5 years old - Microwave Panel lights up, turntable turns, fan works - everything works except it doesn't heat food. Heard a pop, and now it runs louder than before but doesn't heat. Any ideas?

That pop was the magnetron frying. This is a repairable problem, but feirly expensive, around $300 if you have it done by a professional.

Please rate my response if it was helpful to you.

Thanks, Repairman45.

Suggest you pull the plug out, remove outer cover and place a cup of water into the micro. Set power to minimum then switch on and take note if the fan works or not. If not, switch off immediately and have it replaced(magnatron will burn out if left to run without fan.)

Microwave popped and now does not heat

Okay, first we need to separate the situations. You were boiling water on the stove and had the range hood fan running to **** up the steam. Then you put something in the microwave to heat and you heard a pop and then zip-o.

The water on the stove has nothing to do with the situation, the fan you turn on is not part of the microwave, so it has nothing to do with the microwave.

The pop you heard and then the humming suggests the magnetron failed. You said you found a blow fuse and replaced it and still nothing, right? The magnetron is the most likely culprit...I would think it is safe to say that the magnetron shorted and drew enough current to blow the fuse.

Replace the magnetron and if that doesn't work, let me know here. Good Luck!

Everything works except the cooking part/no heating/turntable not turning, help!

you may have gotten a power surge and that can cause some funny things to happen, 1st is there power to the oven, 2nd if so there may be an internal fuse protector built in to the oven, check with the manual for anything of that sort listed. if not you may have to take it in and have it repaired by a pro. there is a lot of voltage in these ovens and unless you know what you are doing a person could get hurt

Heard a loud glass breaking noise, now micro-wave will not heat anything. Turntable works, everything looks fine but no heating. Model#R-1505LK

Does it seems to run louder?

I would suspect a shorted high voltage rectifier diode.
