Well, I'm on my 4th replacement (I think, I lost count) of the control module due to the 2H code appearing. All is well now. My question is that when I removed and looked at the board, there was no burnt solder joint like on the original board. Does anyone have any idea what went bad then? I would like to repair it and save it for the next time the module needs replacement.
Also, I still have the original board. Should I try the Tyco replacement heater relay for that board or is that relay only recommended (by Mr Mark, for ex.) for the more recent boards (my original has the led red lights vs the newer board without).
Thanks for any thoughts on preparing for the inevitable "next time".
