I am having a similar issue to the other questions posted here (frosted freezer, warm fridge). I want to check the defrost heater for continuity, where do I do that? Do I unplug it from both sides and test there? I am not exactly sure where I should put the leads from the ohmmeter.
Answer Hello Chad,
The procedure is as follows:
DEFROST HEATER CHECKING PROCEDURE
Obtain an ohmmeter from your local store. We will be doing RESISTANCE checks. This is the safest way because the refrigerator is unplugged from the power source and avoids the possibility of receiving an electrical shock.
Step 1 Set the ohmmeter scale to the lowest ohms setting and ZERO the meter.
Step 2 Remove one wire at a time, carefully labeling each wire according to the location or terminal marking on the defrost heater. This procedure should assure that the right wire is reconnected to the right terminal after checking or replacing.
Step 3 Touch and hold one ohmmeter probe to one of the terminals.
Step 4 Touch the other ohmmeter probe to the other terminal.
Step 5 The ohmmeter should show a reading between 10-1,000 ohms on the ohms scale. If not, the defrost heater is bad and needs replacing.
Step 6 Reconnect the wires to the proper terminals as previously marked.
