Error code 29

Cause:

Pressure Switch Failed to Close

Solution:

The blocked vent pressure switch contacts have opened.
- Check to make sure the venting system is not blocked.
- Check to make sure the condensate drain is not clogged and is sloping toward the drain.
- Make sure the vent length does not exceed the specified limits.
- Make sure the vent terminal is not blocked.
- Check to make sure the pressure switch tubing is clear.
- Replace the pressure switch if the venting system has checked out O.K. Control will reset once problem is corrected.
