Repeated 24V furnace transformer failures?
Twice in two years, the 24V transformer in my furnace has failed. Both times it happened was after we had been away a couple of days and went to switch the heat back on at the thermostat switch. Our house is about 20 years old but this has just started happening the last two years.
I have a heatlhy 121V present at the input side of the transformer but nothing at the output that is supposed to be 24V. These are the same symptoms as 2 years ago.
What could be making my transformers blow like that. :confused: Is there a heavier duty one available? How many amps does this transformer have to handle?
Thanks,
