Hello I am here to assist you.
Remove the thermostat cover and you will see a R terminal and a W terminal.
REmove the wires from the R and W terminal and twist them together. Let me know if the heat comes on or not.
do you mean to twist red/black wires 2gethr?
How many wires are there?
Twist them together and tell me what happens.
will let u know in just a second...the screws holding the wires in place are really tight...
any concern of getting shocked while doing this - twisting the wires together...?
No this is low voltage wires.
ok, they are twisted together and nothing is happening...
Try tapping on the gas valve with the back of a screwdriver very hard.
with the wires twisted together? or should I untwist them
BAnging on the gas valve caused nothing to happen
It sounds like you need a new gas valve. Place the wires back on the thermostat.
We need a new gas valve even though the pilot is still lit?
Is there any special reason for putting the wires back on the thermostat as well?
Yes because the Main valve is not opening to allow the burners to light.
and what about the wires needing to go back...
No special reason to put the wires back, except the fact that we have eliminated the thermostat as being bad so may as well put them back.
OK, thanks for the help...how much does it cost to replace the valve...and do I need to have a plumber do this or is this a DIY kindof thing?
I would advise you to have a technician come out and replace it. That way he can check to make sure the gas valve is bad.
It usually cost about $450 to replace the valve.
Well, what would cause the valve to just go bad all of the sudden?
wear and tare.
Check the wires to make sure they are not broken or frayed in any place.
It is only three years old
maybe five years old...not used a whole lot either
Three years old and it has a standing pilot light?
what does a standing pilot light mean?
Usually anything younger than 10 years uses a automatic pilot igniter.
It means the pilot flame is lit all of the time.
on all the time? No wires are frayed by what we can tell...it is definately not more than 5 years old
That is unusual.
It definitely sounds like the gas valve is bad.
the pilot stays on and then when the thermostat signal kicks on it lights the burners...but there is no click that happens
And you are sure that there were only two wires at the thermostat? Is the fan coming on?
there is no fan. it is a millivolt thermostat. The model number is XXX 2016
This is not a forced air wall furnace...it just radiates heat
I would advise you to call a tech out to look at it.
Will do..will let you know what the resulting action is.
I was not convinced that the answer you gave me - "it definately sounds like the gas valve is bad" was really what the issue was. Turns out my hunch (probably my hunch leaned this way because you said it would cost $450 to replace the gas valve - more than the cost of the heating unit itself, I might add). Turns out it was the thermo-coupler - a $20 replacement. I was NOT satisfied with your answer and hope that next time you might give your on-line chatters a number of options to investigate rather than just assuming one thing based on a couple of symtoms. ? THIS would be more helpful in the future, since I was asked to give feedback on improvemetn. One last note, If I had followed your advice and "expert opinion", it would have cost me a few hundred dollars more - and I cannot afford that.
I am glad that your issue was resolved. I apologize for sending you in the wrong direction and I thank you for sharing the info with me. This will help me in the future.
Have a great Day!
