I will have that information to you shortly. The error is on the thermostat. This is been happening since we moved this furnace from the garage to the basement.

Sort of tough troubleshooting without knowing the system components.Let me see what I can find

Customer reply replied 7 months ago
That’s it
HVAC Technician: airheatman, HVAC Technician replied 7 months ago

OK issue will be one of the following

1.Bad pressure switch

2.Water backed up in hoses in furnace

3.Issue with draft motor not pulling enough vacuum to close switch

4.Obstructed intake or exhaust vent.

Ask Your Own HVAC Question
Customer reply replied 7 months ago
I emptied out water that was in the draft motor
HVAC Technician: airheatman, HVAC Technician replied 7 months ago

THere should not have been any in there. That indicates either there is a drain blockage downstream or issue with the secondary heat exchanger

Ask Your Own HVAC Question
Customer reply replied 7 months ago
Where is the secondary heat exchanger?
Customer reply replied 7 months ago
Well I added a condensation pump. That helped but still getting water in exhaust blower.
HVAC Technician: airheatman, HVAC Technician replied 7 months ago

Any kinks or restrictions in any of the rubber hoses inside furnace? Also if you can, we might try disconnecting the trapp and making a new trap using tubing to see if maybe the reservoir is clogged letting it back up
