Safety first: Unplug the unit and allow it to cool. The heater area can remain hot for some time.

Step 1 – Visual check: Remove the basket and pan. Inspect the visible portion of the heating element for breaks, blisters, or burn marks.
Step 2 – Check connections: Remove the rear or top cover to access the heater terminals. Ensure the spade connectors are tight and not oxidized. Reseat any loose connectors.
Step 3 – Measure heater resistance: Disconnect the heater leads from the PCB and measure resistance across the element. If it reads open (OL), the element is failed and must be replaced with a compatible Midea heater assembly.
Step 4 – Inspect relay/triac: If the heater tests good, check the heater relay or triac on the main PCB for signs of overheating or cracking. Replace the main control board if the switching device is defective.
Step 5 – Confirm thermal fuse: Verify that the thermal fuse in series with the heater has continuity. If open, replace with the same rating.
