condensation build up lennox G51

[cunko]

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

Thanks
