Locked Re: HT-37 transformer failure due to rapid STBY-->OFF-->STBY


 

Halden,
?
Well, pretty much any relay would work well.? Several years ago, I used a relay out of a parted out microwave oven to replace the hot surface igniter (HSI) relay in a gas furnace.? Those things switch power 120AC @ about 7A to the HSI every time the furnace lights.
?
The relay was a 24vac coil and good for 250VAC/10A? and it soldered right in on the furnace control board.? My alternative was to replace the board @nearly $800? .......I opted for the old relay out of the microwave!!
?
I only like the SSR option if I can find the things for cheap on eBay or other sources.? If you have to buy them new, it's really cost prohibitive.
?
But the key here of course, is getting the 120AC at possibly several amps off the fragile no-longer-available switches!
?
?
Cheers,
?
Rick
