I have Williams Gas Wall Furnaces in my 10 unit apartment building. I know what part is bad but don't know what it is called. The pilot light won't light. The gas guy said in his door hanger that this furnace has a millivolt system. Where do I find a diagram of this furnace with the parts named?

This info is from the tenant. It doesn't appear to be correct?

Williams Gas Wall Furnace model G25SD

Serial # 4985

Thermocouple? But even then it should light as long as you hold the knob down, then go out when the knob is released. --66.226.xx.xxx

These use the common millivolt thermocouple to -hold- the pilot on, if the mechanical gas bypass does not get the pilot you either have a blocked orfice at the pilot - clean with welders wire or too much trash at the gas valve inlet or both. Gas line trash causes many problems, remove the drip leg and dump out the trash within a year of installing anything new to the gas circuit. --76.241.xxx.xx

Virden is right. After that, check the gas inlet pressure. Also the supply tubing to the pilot assembly may have a seperate turn off valve. After cleaning the pilot orfice, I often blow out the pilot supply line with a small air compressor. --173.58.xxx.xxx

HD sells the entire wall furnace for $416.00 Item# 3509622 35KBTU

Furnace Parts.Com sells the igniter module for $221.66 Item Number P321910

If it's a few years old it may pay to just buy the whole thing new ?? --99.151.xx.xx

Thanks all. I found this page.

It is a general controls part/s but not the same numbers as listed in the above doc.

If this is the correct part. At $198 bucks if I need to replace it. I agree with Reid. I would replace the whole shebang.

I'll first try what Virden and Robert J suggested. See if that will slap this furnace into shape.

I checked 2 other wall furnaces to make sure I have the model number correct. YUP it's correct.

I can't find any info on the net about that model number. Weird. I'll check RR's link and see if it shows up there.

Model G25SD does not show up on the link RR posted.

So I called the phone number that Moshe posted (Thanks for that Moshe) and left a message with the tech department I was transferred to. Stating the situation giving the model and serial #'s.

I just received the call back. They have no such model number in their files. The closest model number they have is model 825.

They estimate my wall heaters to be at least 20 years of age. I estimate these wall heaters to be original issue. Installed in 1965. So they could be years older depending.

He told me that the replacement part which is the entire assembly is $422 bucks chuck.

I told him I thought it is the thermocouple that is bad on the old one. He replied that I wouldn't be able to find any of the smaller parts.

He told me that the replacement wall heater they suggest is model 2509622. That after 10 years the furnaces are obsolete. I responded that these wall furnaces are good quality as my 10 units have been running them since the 60's. It's a shame that parts aren't available at a reasonable price. That I wished there was info available online so I and others would not need to bug them with these questions. That's alright he said that is one of things I'm here for.

Again our throw away society rears it's ugly head.

So I think I'm going to swap out the bad part with the furnace in a soon to be vacant apartment and put the new heater in that dwelling.

All this started with the tenant in this apt turning her gas off trying to save $20 bucks for one month. Yeesh hair brained tenants.

So it ends up costing me $400 plus. Ugg....

I couldn't find anything online that was specific to this model, but was hoping that something in the links was *similar* to what you have. And use this to get parts.

Although they change models very often, the internals may be very much the same. Instead of focusing on the model of the unit, how about identifying the actual part that is bad(swap parts with another working until til you find the bad part)?

There's got to be a way to get an interchangable part for this. I still can't envision which part you are talking about however.

How long should a gas wall heater last? My is a Williams around 9 yrs old and now the thermo switch is shutting on and off which effects the heat exchange. Thank you --24.1.xx.xxx
