Service Test - 6: Defrost Heater/Bi-metal - "bi-metal open"
NOTE: If bi-metal is open, it will need to be bypassed for heater to operate.
That means the Bi-Metal has to be frosty for it to CLOSE, which means continuity, and it will turn the defrost heater on.
OR if its not frosty:
To bypass it: a bent paper clip will work, just plug it into where the orange and brown wires connector pin go in the big plastic connector block where the main wire harness connects(LOOK AT THE PHOTO BELOW). I circled the defrost thermostat on the right side in BLACK. I circled the big plastic connector block in RED on the left side.
Just make sure you unplug the refrigerator first before putting that paper clip jumper wire in, then plug the refrigerator in and do TEST 6 and see if the defrost heater comes on, the defrost heater is underneath the evaporator coil, you should feel that get hot in TEST 6. Unplug the refrigerator after you are done with TEST 6, then remove the paper clip jumper.
