If your Merrychef Microwave Oven displays a Cavity Sensor Error, it could be because the cavity either didn't heat by 180°F in 10 minutes or exceeded the set point by more than 72°F during cooking. In such cases, replace the sensor. Also, check that the temperature is OK, examine the heater elements, check the door switch, and inspect the interconnecting lead to the logic PCB.
What to do if my Merrychef 402s is not heating food properly?
If your Merrychef Microwave Oven isn't heating food adequately, it could be due to a few reasons. A possible cause is a temperature sensor fault, so start by checking the convection temperature control. Other checks include the convection motor’s operation, the stirrer's rotation, and performing a microwave output test. You can also use a clip-on current meter to check the current through F7 and F8. Replacing the stirrer motor and retesting may also resolve the issue.
Why is there no display on my Merrychef 402s Microwave Oven?
If there's no display on your Merrychef Microwave Oven, start by checking the cable from the logic PCB to the display to ensure it's properly connected and that there are no disconnected or shorted wires. Also, inspect the 15-way ribbon cable between the Logic and Relay PCBs. Verify the power supply to the Relay PCB and check the fuse on the Relay PCB. If these steps don't resolve the issue, consider replacing the display or the Logic PCB.
