I have a goodman GCH95 counter flow ,turned on for first time this season and got a 3 flash code. it must have ran for awhile because condensation was pooled on bottom of unit ,never had that before-i changed cover pressure switch and put cover back on,turned it back on and it tried to start then went into lock-out.took cover back off and tried it again and it started and ran through complete cycle.checked both switch vac hoses and no water or blockage and noblockage in condensate drain lines HELP
JA: Did you double-check the thermostat? And what about the unit's filters?
Customer: thermostat works fine and new filter installed
JA: Do you plan on doing the work yourself?
Customer: yes
JA: Anything else we should know to help you best?

Hello,

My name is Billy. Is the furnace vented outside with 1 or 2 pipes?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
no just wanted to let you know the furnace and a/c is only 2 years old
Customer reply replied 1 year ago
2-pipes,one for combustion and one for exhaust
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

thank you.

If you remove the combustion air pipe does the furnace run?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
No it does the same thing,it only runs with the cover off,when it does stop burning it makes a loud banging noise,could I have a cracked heat exchanger-it is only 2 years old-still when cover is on and I run furnace goes back to a 3 flash code
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

when you cleared drain...did you use a shop vacuum and apply direct suction to the furnace itself at drain point?

Ask Your Own HVAC Question
Customer reply replied 1 year ago
All drain lines were removed blown out and checked with light,both pipes were checked for blockage. I also checked inducer blower for blockage and seal all are good

Is there a stain pan in heat exchanger compartment
Customer reply replied 1 year ago
I ment a drain pan
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 year ago

my concern is not the drain lines..it is the secondary heat exchanger inside the furnace...did you apply suction to the drain coming from furnace?
