Defrost Heater (single element) burned out

Unplugged fridge. Cleaned out freezer. Removed four evaporator cover panel fasteners and removed evaporator cover panel. Defrosted ice from evaporator with hair dryer and window fan. Removed old burned out heater by removal of 2 fasteners. Demated blue and pink wire connectors from old heater. Re-routed blue heater wire to same side of evaporator unit as pink wire. Plugged blue and pink wire connectors into new dual element heater. Re-installed heater fasteners. Re-installed evaporator cover panel and re-installed four evaporator cover panel screws. Did not need white wire extension supplied with kit. Simple directions, easy to follow.

When I plugged back in the fridge power cord, the fridge compressor ran for 10 seconds and then stopped for 36 minutes. As it turned out, the defrost heater timer switched off the compressor and ran the defrost heater for the designed 36 minutes. After the defrost cycle completed, the fridge compressor began to run normally.

So far, no ice build-up anymore in the freezer. Looks like all is back to proper functioning.
