Hi , I have a *****50000 btu direct vent wall furnace model 867.736434. The pilot will light and the gas comes on.. The blower fan does not come on and the gas shuts off after 30 seconds..Had a heating company come in and they changed a few parts and I still have the problem...They said the vent may be clogged but they dont climb over 20 foot ladders...I broke out the ladder , took off the vent and looked inside ...No clog..Im lost and still have no heat ..Any help is appreciated.

Because they think its the vent and they wont climb a 20 foot ladder under union rules. They replaced the thermocouple and the part with the flame adjust switch on it..It is a ***** direct vent gas wall furnace...

gas supply stays conslant until the blower tries to turn on...Was told by another that this could be a venting problem....Does this seem correct???

"It could be that the heat exchanger is broken and the fan blows the pilot out"
If the fan never comes on, then how would the fan blow the pilot light out..It seems to go out mechanically and not with wind..And, yes, I agree that the tech should have eliminated many problems...This is why I usually never call a tech and look to these forums...Many good people here that may have had the same problem...

" That is the usual result of playing
"YEAH BUT...."
Make several suggestions,,,, don't respond to the suggestions .... tell of other problems ... game goes on."

I still cant see in these posts where you mentioned to check voltage...Only see where you told me to check gas pressure
...Anyone else want to help as this guy dont read to well..as I said in all my responses : I did as was suggested and problem persists
If you dont know the answer and could only guess, then dont respond and waste all of our time.

The man was obviously just trying to help you and your rudeness was not warranted. You never posted a make model of the unit. I can't see it from my house. Look at the original user installation manual. Go to where it says sequence of operation and try to figure out what's not happening in your case. Nobody said troubleshooting was easy. Top heating techs get paid good money because they have good troubleshooting skills. Sounds like from your post you called in someone who was not experienced enough.

I had a similar problem a few months ago. The heater would kick on fine. The gas would ignite, heat up ok, then when it was time to blow the air out, the gas would go out and no air would blow. I had a repair guy come out and tell me it was a faulty blower. I tested the blower to verify it had power going to it, and it did. I took the blower out, and found it had froze up. I ordered a new one and installed it, and it corrected the problem. You might want to check out the blower. After taking it out, you should be able to turn it with your hand. (make sure you disconnect it first from the electrical) If the blower doesn't turn that could be your problem. I think it's worth the $30 to have a repair guy come out and diagnose the problem for you, and then you can decide whether you want to mess with repairing it yourself or have him do it. Good Luck!
