    How's it been running? Did you know that there is an 8-10 hour timer on it?

    I went another route I bought a Chinese knockoff. It installed in the same footprint and has a separate controller it works great I paid $175 on Amazon which was cheaper than all the parts for my old one

    My guess is you checked for the parts at Thermo King, and they were pricey? I have never worked on my heater yet, but plan on working on it, if it gives me any issues this winter.

    I personally have never purchased parts for the heater at Thermo King, but I do know they sell Espar heaters.

    How old is/was the Airtronic? The newer ones can display faults on the control panel; the older ones required a separate tool for it which works great... when it works.
    I have a bunch of those sockets. I'll try to take count of just how many I have and I'll make them available if somebody needs one.
     
    earnies2 and PE_T Thank this.
