I searched everywhere and couldn’t find where the electronic thermostat lives in my UW56!
Today I started tearing things apart, and noticed a clear window at the bottom of the heater/blower plenum. When you power up your Toolcat and turn on the AC, you can see fault code pulses from a red led through that clear window.

1 pulse/second = Temp sensor open or short
2 pulses/second = Clutch open or over current
3 pulses/second = Clutch short to ground
