I have been playing with my heat pump (Amana ARUF-049) every winter & this year is no different.
I installed a Honeywell programmable T-stat at the beginning of last winter and the system muscled on through the summer heat without an issue.
The primary side of the x-former burnt out this round. I replaced it last night and it went out shortly afterwords.
Here is my thinking, after my all nighter - I incorrectly installed the t-stat, by connecting the "C" Blue wire, when I was directed not to, per the directions... It just didn't make sense last year.
My new direction of pleasure - (1) Disconnect the "C" Blue wire at the T-stat, (2) perform a short test on the wires and (3) replace the transformer again.
Can anyone reflect on or confirm my diagnosis & theory of my corrective * I greatly appreciate your time and expertise, from one & all, as I am a true Jack of All Trades, yet Master of None.
