Nortek/Nordyne/Tappan/Westinghouse Furnace Question

724 Views 2 Replies 2 Participants Last post by  homerehabguy
I have an older Westinghouse furnace Model no. 904183. Serial No. G6TA072C-12B. My high Limit fan switch went out two years ago. An HVAC tech replaced the part 626526 which was rated at L280-20F which I assume is 280 degrees and 20 amps.

It was replaced with a 290-30F switch, which went out last Saturday.

Nortek/Nordyne told a North America HVAC representative that part 626526 was no longer made and was not in stock. Nordyne recommended part no. 626464 or 626464R.

So, I bought two of those, just in case one went out. Installed it tonight with one problem.

The new switch is much smaller, so the old holes in the assembly plate won't hold the new part.

My question: Do I just drill new holes and mount it? Is there a universal bracket I can get to hold the new switch in place?

It seems to be working even though it is only rated at 135-15F.

By the way, it took me nine hours of driving plus internet searching for this part as the industry went nuts instead of using the same basic parts for EVERY furnace they make, they made new parts for each furnace.

Well, NorthAmericaHVAC's rep. had Nordtek's furnace parts manual in front of her. The part my furnace required was a 135-15F. They don't make part no. 626526 any more.

She also called Nordtek/ Nordyne and asked a tech there who gave her the replacement part number(s).

The part is working.
