I have a furnace with a standard pilot. The pilot is on but the unit will not fire up when the thermostat is turned to heat. There is a click at the thermostat but nothing happens. I have wired across the red-white and it makes no difference. The blower works if I turn the switch from auto to fan. Any help will be appreciated.

Youu have a meter to check power going to the gas valve?

Make sure the gas valve is "ON", not pilot.

With the tstat calling for heat. do you read 24V on the two wires at the gas valve.

and if you read 24volts at the gas valve, then you need a new valve.

Set the meter around 120 volt AC range. and put the probe on the gas valve where the wires meet.

So I touch one probe to each of the 2 white wires on top of the valve?

Find the transformer and see if it has 24V

It seems the transformer is behind a metal case. I think this may be beyond my comfort zone on electricity. So what are the possibilities I am looking at on the repair? Thanks
