pulled out the plug to heater, thermo and fan
unhooked fan and heater
back-probed the plug for the wires to thermostat - read 9.9 when warm and 11.3 when in ice water
this sounds like a bad thermostat, right?
when i pulled out the fan for general cleaning a white plastic tube fell out with it - image attached - what is it and do i need to worry about pulling more covers off to put it back in place?
