Yes I do.
It has fan/on and getting nothing at all. Pilot is lit and the fan is working when I manually turn on the fan switch at the furnace.
Did that...still nothing
Ok, now remember I don't have a manual, so I am going to be doing some of this as general troubleshooting. To start with, How old would you say the furnace is and does it have a control board on it? If so any led lights that might give us a flash code(error code)?
It is real old so no led lights. I would say it is from the sixties.
Yeah, that is about age I expected it to be. So we just have to go a step at a time. Lets go to the furnace and locate the transformer.On low voltage side we will have two wires. One is common and goes straight to the gas valve, fan relays, etc. The other goes to R at thermostat and comes back from thermostat on W when thermostat calls for heat. So lets start by making sure we have a circuit closed to that point. In other words determine which is COMMON. Put one meter lead on it. The put the other meter lead on the white wire coming back from thermostat and on call for heat we should read 24 volts between common and white. We will go from here.
Just to confirm what setting should the multimeter be on... DCV 20?
ok put it on ACV200 and it is reading between 25.8 and 25.9
Yes...I put one meter lead on the component (blk wire) and one on wht wire and it is reading 26.4. P.S. the gas valve where the other wire goes to is really hot.
Yes, has a standing pilot and it is lit.
This is pointing to a defective valve. Do you have a combination fan/limit control like this with a dial?Also how many terminals are used on the gas valve?
It is quite a bit different but yes and the fan control is set at 110.
There is a dial that says "fan off temp" and goes from 60-130. I tried to turn it both ways and nothing happened.
Yes 2 terminals
So it is a defective gas valve??? Also can I replace it myself and do you know the price range for a new one?
If you can get the model off of the valve, we can Google it to locate one
McCorkle 24v 60cycle .42amp 1/2 psi Model#V472. That sound right?
ok thanks for all your help.
