Question:

We tested defrost heater already and there was no problem with the heater. How to test the defrost timer? Thanks.

Christine for model number Csx22gayaww
Answer:

Hi Christine, Thank you for the great question, Step 1: Unplug the refrigerator. Step 2: Disconnect the wires from the timer and timer motor. Remove the timer from its brackets by backing out two retaining screws. Step 3: Test the defrost timer with a VOM set to the RX1 scale. Clip one probe of the VOM to each defrost timer -- not motor -- wire, and turn the timer control screw shaft until it clicks. If the defrost timer is functioning, the meter will read zero. If the needle jumps, the defrost timer is faulty. Replace it with a new one of the same type. Step 4: Connect the new defrost timer the same way the old one was connected. Hope this helps!

Question:

Freezer cold, but refrigerator warm

Jim for model number TFX22JWXDWW
Answer:

Hi Jim, Thank you for your question. There are a couple of parts that could cause this issue. Your defrost timer is one of them. I would also suggest checking our your defrost heater, defrost thermostat, and your run capacitor. You can test all of those parts with a multi-meter. Good luck with your repair.

Icemaker stopped working,warm fridge,

first i entered the symptoms into your site and the culprit was gonna be the defrost timer or defrost heater-thermostat. I ordered the parts and they arrived the next day even though I didn't pay for next day. Defrosting the freezer was what took the time.After it was thawed it only took about 15 minutes to install the heater and timer. Am happy to say I have all the ice I need and your diagnosis was right on.
