Bad honeywell valve? or igniter?
 
I have a Tempstar heating/AC unit in my home ... (with Honeywell valve model SV9500m-2682).

When I turn on the heat, the only thing that runs is the induction fan(or whatever it is called), it just stays running all the time, nothing else ever happens. BUT, the unit for no apparent reason WILL run properly every once in a while.

I checked the induction fan vaccuum diaphram and switch and determined both items are working. When the fan comes on, the switch closes.

Do I have a bad honeywell valve or is a bad igniter a more likely culprit?

What is the procedure to troubleshoot? is there a way to manually check the igniter?

opinions?

Welcome Skid:
If the igniter is visible during the cycle it should be glowing red. If it is not visivle, a continuity test with your ohm meter should tell. They are notorious for getting a crack in them and not working, but then it would not ever work. Also, you could check for a crack or hole in the heat exchanger.

When the fan is running, such as it does before firing up, gently give the wires a wiggle/bump, going into the control valve. The Heil furnaces (not sure all the models, but same basic units) had this issue a few years ago, and it was the main tiny circuit board in the control valve, where the wires connected inside.I changed my vacuum switch etc, and found a position if the wires were tied up at the perfect angle, the furnace would fire everytime, yet not a reliable fix if planning to go away for a period of time. There was a recall for these valves that the manufacturer sent a memo to EVERY dealer to change them out, and were reimbursed an hours labour as well, yet many would try and get the service call and charge for the valve at retail cost, even though it cost them nothing. I got into a pissing match with the local clown here, since he got one service call and fixed nothing. I contacted the manufacturer and got the scoop from them.They ended up sending me the new valve directly and a freind/gas fitter installed it and worked fine since.

Igniter Plug Short
 
Wow! I ran across this forum while searching for a replacement circuit board for the Honeywell SV9500M Gas Control Valve. A new Gas control valve is about $200. Mr. Wienerwater is dead on w/ his diagnosis. I have been tying up my harness up over and over. It has got to the point now that adjusting the wire harness will not work for long.

Mr. Wienerwater - do you have any additional information about the recall? Recall #, phone number etc.?

This looks like a great forum!

Sent you a PM, Blueforester.I ended up calling a dealer about 400 miles away, since he knows it won't hurt his business locally sharing info so far away and got the contact numbers. I know the valve came from Tennessee I think it was, not 100% if it was Heil/Tempstar, or Honeywell, but will try searching who is where should give me an idea.

UPDATE!!

Try this link, it's for ICP (makers of Tempstar, Heil etc) out of Tennesee
http://www.icpusa.com/ or call 800-649-4706 Bottom left of the page has a Product Safety Recall button, which will open a page with contact numbers as well. Hope this helps anyone.

Recall on Gas Valve
 
Thanks for the reply. I have alerady tried the link you posted. The HVAC unit installed is a Heil. The heat exchanger was made by Intercity Products, which has since changed names. I have tried to talk to Honeywell but the refer me to the furnace manufactor. ICPUSA recall will not give me any info and refers me to there distributors. The distributor and some of there contractors I have called are aware of the problems with this gas valve but have never heard of the recall for this gas valve. It looks like I'm going to have to purchase one myself and have it installed.

That is EXACTLY what is happening to mine. When it stops working I wiggle the wires till I see the igniter start to glow.

I guess I will see if Honeywell will send me a one.

Check It 12-07-2007 08:27 AM

Have the same issue. Does anyone have further information on this? I checked the link above and the CPSC web site (search for Honeywell, Heil, and model number) but nothing comes up.

I would be surprised if it was a "recall" as it doesn't seem safety related but more comfort/annoyance issue.

So far, I have a call into the distributor and it is checking on the status of anything with the valve number, but have not heard back as of yet.

I have the same unit/problem. A friend who is a HVAC Sales/Installer person showed me that if I gently "push" the connector into the valve (on a horizontal plane; not down into the unit), the ignitor would light and the glow would occur and then the furnace would heat. I have a continuous fan blowing right now, just no heated air.

Problem is that this has occured for about 6-8 months and the temporary remedy doesn't work at all anymore. I am very green to all of this so can anyone tell me what to expect the replacement costs of this Honeywell smart valve to be so I do not get taken advantage of? Thanks!

I had the same problem as you guys starting about 18months ago. The same remedy of jiggling the wires worked for along time. Finally it quit working. One year ago I took the plastic housing off to find that the solder joints holding the socket marked control had come loose. I took it to the maint. man I work with and he re-soldered it for me. About a month ago I started having the same issue again, intermitantly. Well today it's dead and I am gonna take it back to the maint. guy I work with. If that doesn't work then I will have to replace it. I have seen a couple different forums and this seems to be a very common occurence with this unit.
