Kcredchief for Model Number JVM1790sk01 The model is a micro/convection oven combo. The unit is fine with door open. When door is closed it makes a loud hum coming from the transformer like there is a short. It stops as soon as you open the door. You can turn it on and everything appears to be working. The bottom of the unit gets hot as well when the door is closed. I checked the door switches with a meter and they appear to be working properly. Any advice what parts I should buy to fix this? You response would be greatly appreciated. The unit is only three years old. Thanks
Answer KCredchief, The most likely issue will be cause by the monitor switch shorting out and allowing 120 vac to get to both sides of the transformer. With this issue, it is recommended to replace the monitor switch WB24X25397 and transformer WB26X21108 at the same time due to possible damage from getting 120 vac on both legs of the transformer.
