Thermostat Repair

White-Rodgers 1F90-51/-60 digital, programmable thermostat from about 1987.

Mea Culpa: I left 3 Duracell AA batteries in the unit for years and years. Corroded the little spade connectors so bad that 2 broke off.

I jerry-rigged something that got it going again, but it's so flimsy that it could fail anytime. And it's cold, Cold, COLD nowadays (midwest US).

It looks like a common design. Copper spade connectors that mount in a groove in the plastic on one end, extend to allow contact with the battery poles on the other.

Any suggestions on how to do a substantial repair? It's a great old (4 wire, single-stage) control, there's a zillion of them around here yet in service: in friends houses, businesses, etc. Moreover, I got nooooooo idea what t-stats they got on the market currently or how they might wire.

Thx, P

You are smarter than po' me. And you plan better. :-)

No problem with the pic, and I -very- much appreciate the offer, but I dunno we should have to ship across 3/4 of the planet for this (I'm in midwest US).

Let me fish around a bit. I'll get back to you.

Thanks, P

I salvage battery contacts from discarded equipment just for this reason. If you can upload a photo of the old contacts, and provide the dimensions, I can try to match them with something in my junk box, in which case you can have them for the cost of postage from Australia.

You can probably order replacement parts from the manufacture.

The more complicated alternative is to look at some of the local electronic parts dealers and see if you can match up a set of spade lungs. You can also get some copper alloy sheet metal of the same gauge as the origional spades, and make your own pieces.

Another solution is to get a battery holder at an electronics parts dealer and see how you can innovate a new battery holder for your unit.

Personly, I would see if I can buy replacement parts from the manufacture.

I got some sheet brass that might be suitable.

Don't know where I'd put the holder save just hanging it inside the wall.

Oh, I didn't neglect that possibility. Couldn't find anything on the net, tho.
