Also there must be some sort of appliance moving union that should move those things around before they are worked on. I mean you could crush your toe easily moving a waterheater should certainly leave that up to the pros Quote Link to comment Share on other sites More sharing options...

Tomas. Posted April 26, 2018 Author Share Posted April 26, 2018 Well this morning I gave the gas valve a few persuasive taps and no dice. 24v goes into the valve and doesn't come out. I deal a lot with Nat gas at work so I am not worried about fucking that up to much lol. Quote Link to comment Share on other sites More sharing options...

Did you check the coil on the valve for resistance like I said? Also when the valve is energized it should be magnetized. You should be able to take a screwdriver and feel the magnetism when the valve is supposed to be open Quote Link to comment Share on other sites More sharing options...

USA Contributing Member $poorsledder$ Posted April 26, 2018 USA Contributing Member Share Posted April 26, 2018 Shit, something I could have added valuable confusion to and I missed out. Wasn't able to take a break at all this morning. 1 Quote Link to comment Share on other sites More sharing options...
Tomas. Posted April 26, 2018 Author Share Posted April 26, 2018 I checked for resistance. It was open both on and off Quote Link to comment Share on other sites More sharing options...

Tomas. Posted April 26, 2018 Author Share Posted April 26, 2018 Is there anyway I can make sure it is the valve? I found one but it is $260. I am in trade school right now and would prefer not to be wrong and waste the money lol Quote Link to comment Share on other sites More sharing options...

Tomas. Posted April 26, 2018 Author Share Posted April 26, 2018 The blue wire going to the valve reads 25v. The grey wire reads 0. When checking continuity across the valve, it reads open. The blue wire comes from the pressure switch and the grey comes from these two blocks. One is a transformer and not 100% on the other but the wiring diagram is on page one of that helps Quote Link to comment Share on other sites More sharing options...

You have 24V accross the valve, it should be open regardless of any other sensor. Quote Link to comment Share on other sites More sharing options...
2strokemerc Posted April 26, 2018 Share Posted April 26, 2018 Did you move the red lever to off on purpose or by accident? It should be on. Quote Link to comment Share on other sites More sharing options...

Tomas. Posted April 26, 2018 Author Share Posted April 26, 2018 Lol. I have the gas shut off to the furnace. I have had to pull the valve off to change the thermocouple and such so I have it off to be safe till it get it fixed. 1 Quote Link to comment Share on other sites More sharing options...
sledderj Posted April 27, 2018 Share Posted April 27, 2018 Pull the wires off the gas valve. Measure the resistance across the two terminals. If you reading an open circuit ("1" on your multimeter) then that tells you the valve is futched. Quote Link to comment Share on other sites More sharing options...

He'll get 24v to the valve when it calls and it doesn't fire. Solenoid in the valve is fucked. Quote Link to comment Share on other sites More sharing options...
Sal Rosenberg Posted April 27, 2018 Share Posted April 27, 2018 You look at all of the condensation drains and make sure everything is still draining like it should and not backing up ? Can you hear any water in the fan motor when it tries to fire up and then shuts off ? All it takes is a small amount of condensation to back up into the fan motor and that thing ain't gonna start 1 Quote Link to comment Share on other sites More sharing options...
f7ben Posted April 27, 2018 Share Posted April 27, 2018 The coil is open.....its a bad coil. You may be able to change just the coil portion of that valve. Take that shit apart and see !!!!!!!!!111 Quote Link to comment Share on other sites More sharing options...
