Hi,
Woke thismorning to a cold house and a blank thermostat. After some investigation , found the 24vac at the thermostat and the furnace terminal to be dead. Reset the breaker and the furnace tried to fire. Blower ran, inducer ran igniter lit and burners ran for about 5 sec and shut down. Flashed code 33 after a few tries it began to flash 13. Little more investigation into code 33 led me to find the condensate trap pluged and drained about 1/2gallon of water from the system. Cleaned all hoses and cleared the blockeage and its been running fine since. The question I have is will the lockout code13 cause the loss of the 24vac to be shut down to tbe thermostat circuit or do I have another intermittent issue?

Blower replaced in 06
Inducer in08
Heat exchanger in 08
Heat e changer was pluged no doubt caused by the blocked condensate trap. The debris cleared from the trap looked just like the stuff blocking the origonal heat exchanger.
Note: unit running on propane.
Any thoughts?
Thanks
Jeff.
