Appliance Tips of the Week...
Microwave Sparks
Q - When there is small amounts of food in the oven, arcing occurs right behind the plate where the wave guide comes into the oven. Sometimes it works well and sometimes you can't even put in a bag of popcorn. Any ideas? Could food have 'dripped' in here and be causing a microwave short?
A - Yes! Food splatter or drips can continue to cook and will carbon over creating sparks/arcs from the wave guide cover. Usually can clean up the food on and under the wave guide cover, if the oven liner has been damaged we usually lightly sand and touch up those marks with touch paint. Do not let it go for too long as damage to the magnetron end is possible as well
If the wave guide cover has been damaged, replace it!

Microwave Light Replacement
Q - While trying to change the light bulb on the oven, the bulb broke. When it did, it threw the circuit breaker and the whole oven went out. After resetting the breaker, everything on the oven works except there is no power to either light socket. Any ideas or suggestions on what to replace?
A - You tried to change the light bulbs with the power still on.....tsk tsk!!
Hate to say this....but you probably blew out part of the circuit on the smart board ( the brains behind the key panel you touch ) when the short blew. The light relay on the smart board may have been damaged but 9 out of 10 times when I check them, the board itself is damaged.
With your full model#, you can check prices on that part.
Bottom line....when changing any light bulb, remove the power first!
