Question about Sharp Microwave Ovens
Was working fine, then one day out of the blue was unable to heat or defrost. Clock works and all functions can be obtained but when Start button is pressed oven starts to rotate etc but does not heat or defrost as required.
Have had micorwave just on 4 years and have not had any other problems with it.
Generally, the most common causes of a failure to heat are:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part (such as a shorted diode)
