Why dosen't my furnace start up?
Can a thermostat be bad even though it appears to work?


Pilotstat has been changed
New thermocoupler installed
Pilot light light up OK

When thermostat is turned up you hear a click but furnace burner dosen't light up.
What is the problem?

Check the transformer for 24 volt output.
