High voltage parts are suspect. Need to put a voltmeter on the input (primary) side to the high-voltage transformer (big heavy iron thing in there) Should be getting 120Vac when it goes to cook cycle. Don't touch the other (high voltage) side of this transformer. If the power is there, you are looking at replacing high-voltage capacitor and diode. If that doesn't solve it, then it needs a new magnatron. Its affordable if you do it yourself - buy the part on EBAY - lookup "universal magnatron"
Hope ya fix it!

Grease dripping from bottom of microwave


sometimes when a microwave is mounted above a range some people dont always consider that you have to take into consideration that you have to go by the heat rating guidelines because it will melt the white lithium grease off the gearing and it can possibly melt some of the protective coating from the circuit boards so check if it is rated to be placed above a range and go from there

Microwave Won't Heat


Check the door safety interlock switches. Be careful of the capacitor, potentially dangerous.

If the switches dont make a connection, the magnetron will not energize ... no heat

Danby microwave does not heat food and makes loud constant noise


IF the noise is a sound coming from the oven area, its the megatron tube. Typically, replacing the megatron tube is more expensive than replacing wiht a new unit and a new warranty.

My microwave heats but shuts off due to the fan not coming on


A little late for a reply; you probably have replaced it by now.

I suspect it shuts down because the fan is no longer turning on and there is probably a thermal shutoff switch near or on the magnetron to prevent the chance of fire.
