Maha for Model Number TFX22PRXDWW I got the part defrost heater. How do I test the old one and make sure that is not defective? I already installed a new timer control.
Answer Hello Maha. You can test the heater for continuity. It should read closed for continuity. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.
