Refrigerator not cooling. how to check resistance through heater coil on amana refrigerator

Check for a failed evaporator (cooling coil) fan motor or iced up evaporator due to a failure in the defrost timer, thermostat, or heater.

Hello,
The answer to these questions lies in the way the freezer/fridge combo works. The freezer is where the cooling coils are located. Then air is moved over the coils and circulated through the fridge side by a small blower or fan. The problem arises when the air is not circulated for some reason.
The reasons the air is not moving is usually two reasons The fan or blower has failed. The coil is covered over with ice and blocks the air flow.
The first reason is pretty simple to fix, you simply replace the air circulator and things are good again. The second reason can be more difficult. 1. The timing device that runs the defrost cycle of the refrigerator is defective. 2. The heater coil that melts the water is shorted or not working
Usually the first thing to check is the heater coil. If there is resistance through the coil then most likely it is still good. The timing device can be an advanced defrost control board or a mechanical timing device. If the heater coil checks out to be good then the problem should be the timer.
For most situations, unplugging the refrigerator and allowing it to defrost on it's own will get you going temporarily, till parts can be shipped to you. That will melt the ice and give you a few days or a couple of weeks till it ices up to the point where it will not work again.
So you can see here, the problem can usually be traced to one of three things. The fan or blower The timer device The electric heater coil By methodically checking these parts you can isolate your problem and fix it.


Good luck in solving the problem....

Take care.

The most likely cause is a bad defrost heater. (the part at the very bottom of the cooling coils with electric wires going to it. You should ohm check the heater. If there is high or infinite resistance, replace the heater. If there is low resistance across the heater, it is good, so replace the thermister instead. (about an inch and a half long white pencil shapped item with two white wires protruding from it located at the very top of the cooling coils)

Check the BLUE wire from the temp control to the ORANGE wire of the defrost timer for continuity. That is the complete fan circuit. You should read the resistance of the Evap fan motor. If you do not read resistance suspect the pins of the evap fan motor connector or... the Unbilical harness from near the evap to the icemaker and the evap fan. The connector pins of the Evap fan motor connector (Freezer connector) are notorious for failing.

Good day,
The main heater is a double loop calrod unit mounted to the bottom of the cooling coil located behind the rear panel in the freezer panel.
You can access it by removing the rear panel and if necessary melting any ice or frost built up.
It should be noted it fails rarly, so you should check it with an ohm meter before replacing it.
Here's a picture.
