Furnace repair parts needed
QUESTION:I have a wall furnace, Williams Deponair, installed in 1978. I am
trying to locate some replacement parts.
First is the gas valve, listed as Control Valve V5267 on the manual.
This was replaced several years ago with a Robert Shaw 7000 SRLC, that
also has the following numbers 739-351-003.
Second is the thermocouple, listed as Thermocouple I.T.T. - C.C. 2600G
18 Lg.
The last time the unit was serviced was due to the pilot light not
able to stay lit. The local service guy didn't check anything but
just replaced the gas valve and thermocouple. I really wondered at
the time is both were bad or it was just a fast way to make a buck.
I would like to locate a replacement thermocouple to have on had
before the cold sets in so if the problem happens again I can at least
try to replace just that.
Any suggestions? Do gas valves really go bad? First was in for 15
years, next one installed 3 years later. Any idea how to find an
exact replacement thermocouple? Can't find a listing for ITT
thermocouples.
ANSWER: Yes gas valves do go bad, although not too often. I would guess both
were replaced because it has been proven cheaper for you than to replace one
only to find out in a day or two the real cause was the other. The cost of
the service call makes it cheaper often to replace parts than to chance
coming back.
The thermocouple is almost certain to be standard. Take the part
information and any measurements (photo?) to a heating parts store (even
places like Lowes are likely to be able to handle this one) and see if they
can ID it.
