Question about Hotpoint RVM1435 Microwave Oven

1 Answer

Won't heat, works otherwise

I recently got this oven from a contractor who replaced it for a customer. They claim it worked fine until there were some bad storms in the area one night. Now when you turn it on, everything seems to work fine. You can hear the distinctive sound of the magnetron's deep hum, and when running it on lower power settings, you can hear the magnetron turning on and off as it should. Trouble is, it doesn't heat anything. My question: How do I know for sure if its the magnetron? Could it be the HV capacitor instead? What else could it be if not those? Thank you

It's likely to be the magnetron or a bad connection on the FA terminal of the magnetron, but it may be a bad connection or relay on the control board.

Can two separate convection units (microwave and oven) be combined/joined into one cord and plugged into one outlet and BOTH work efficiently? The contractors I hired combined all wires to both unit


You need to have the contractors return and troubleshoot the problem free since they told you they both worked when you purchased them. There's an implied warranty here. The two ovens should have been tested before the contractor left your house to prove they both worked together.

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.

Hi, Look at the home breaker box or fuse box to check for a tripped breaker or blown fuse. If your oven is not heating because there is no power, you may need to replace a fuse or reset a breaker. Also check the power outlet to confirm that the oven is plugged into the outlet securely.


Press the "START/ENTER" button to get the oven to heat after selecting your temperature, if you cannot get it to heat. If you do not press this button within five minutes of setting the temperature, the oven heating cycle will automatically be canceled and the oven control panel will return to displaying the sign.


Calibrate the temperature setting on the oven if it is not heating at a temperature that you like. Do this by holding down the "BAKE" button until the current calibration setting appears, which will be a temperature followed by "CAL." Use the up and down arrow button to increase the temperature and press the "START/ENTER" button once you are done. You can increase in five degree increments up to an additional 35 degrees.


Call the Whirlpool customer interaction center at 800-253-1301 if your troubleshooting fails to fix your heating problem. The customer service representative can give you contact details for a local service technician so that you can have the oven looked at by a professional.


Hope it helped

This may sound crazy but I had one do the same years ago. I cleaned the touch board with glass cleaner and would work fine until got dirty again. Won't hurt to try!
