Hi I'm going to try to help you out. Do you have access to a volt/ohm meter?

If you switch the thermostat fan setting to on, does your blower start up?

Customer: replied 1 year ago.
what else to check
Expert:  D.E. Anderson replied 1 year ago.

I just wanted to verify control voltage is present. Is the pilot currently lit?

Customer: replied 1 year ago.
pilot is lit .there is 24 volt on the transformer up to thermostat . I replace the thermostat new wires to the thermostat because wires were old I install a new transformer and a new inside blower motor relay because they were burn took a video and picture to sure that all the wire were put back in the right place.there is 24 volt going to the thermostat .
Expert:  D.E. Anderson replied 1 year ago.

With a call on the thermostat check for 24v on the gas valve. I trust ykuwired everything as it was as you said you took video to ensure that.

Customer: replied 1 year ago.
there is 24v at the gas valve . This has me pulling my hair is so crazy.i did 40 years diesel mechanic much easier.
Expert:  D.E. Anderson replied 1 year ago.

Lol. So you have 24v on the gas valve but no gas flow and the pilot is lit correct?

Customer: replied 1 year ago.
still lit
Expert:  D.E. Anderson replied 1 year ago.

Then you need to replace the gas valve it's either clogged or stuck closed

Customer: replied 1 year ago.
Can the gas valve be clean or not or that is not save to do.how do you check the valve to see if is stuck or clogged
Expert:  D.E. Anderson replied 1 year ago.

Well if you tap it while 24v is applied and it opens that verifies that it sticks. But that won't always make it open. You can remove the gaspipe from the inlet and check that screen but that's the extent to which that can be checked. Disassembling the valve would be unsafe.
