blower does not run automatically on lennox g40uh(x) furnace
The thermostat sends the signal for heat and the exhaust fan goes on, but the blower fan does not start and the furnace does not ignite. The fan blower does work if I manually turn the fan to on (instead of auto) at the thermostat. I tried tapping on the limiters, but it doesn't seem to help. Any suggestions?
