THERMISTOR ASSEMBLY,NTC

There are 3 different thermistor parts for this model. The CH02 error could refer to any of them. They are inexpensive so get all of them. Replace one at a time until the error goes away. It is a straight forward sort of thing. Turn off the power. Remove lower screws on the cover and lift the cover from the bottom up, unplugging connect ... Read more ors as you go. Each one is a different size and keyed. You can't mix it up. I used the camera on my phone to identify the order of power leads and general lay of connectors and routing of wires. Look for the circuit board on the far right. Unplug the forward most connector on the bottom. This will give the circuit board room to slide out of its plastic housing. You can now access the remainder of the plugs on the bottom. Putting the cover back on is the hardest part of the whole thing.
