I have had the Lennox G51 for about seven years and have had no issues until this winter.
I am getting an excessive build up of condensation inside the unit.
I have drained and cleaned the trap along with checking the hoses and everything is clear.
I am draining about 1/2 a gallon every eight hours.
When the induction fan kicks on there is a vaccum generated through the drain lines. Is this normal?
Any suggestions would be appreciated
