Is it necessary to take an extra care in replacing a thermal fuse Why?
Replace blown fuses when necessary This is thermal fuse protection at work. It keeps the appliance from experiencing insulation damage, or worse. You may not feel compelled to replace the thermal fuse right away, but without it, you are actually in danger of having a fire spontaneously start in the vent.
What is thermal fuse protection?
Thermal Cutoffs (Thermal Fuses) are devices designed to keep components safe in situations when an excessive temperature occurs. When the rated functioning temperature of the thermal cutoff is exceeded, the device will fail open in the electrical circuit, breaking the flow of current.
When to replace the thermal fuse in a refrigerator?
If your refrigerator/freezer stops running and cooling and will only work after it is unplugged then plugged back in, replacing the thermal fuse (thermistor) may be the answer to your problem. Here’s how to check the thermal fuse to see if it needs replacing.

Add the total up. If the total surpasses the total amp rating of the breaker or fuse, the refrigerator likely blows the fuse or trips the breaker when the compressor turns on. To remedy this, replace the fuse with a fuse rated high enough to power the total circuit or eliminate items from the circuit permanently.

What does a thermal fuse look like in Dometic?
Kirk, your manual is from an older version. Ceeminor, the thermal fuse I’m familiar with looks like a resistor, connected via spade terminals, with a clear plastic tube to protect from short circuits. This is represented in your schematics by item “Y”.

I chased the wire from the 12VDC terminal block all the way into the inside of the back of the refrigerator and lose it there as I can’t see the interior part of the refrigerator. The box that has the fire inside. Base of the chimney stack. Thanks for everyone’s help!
