E0F Condensate switch open - high water in drain pan

What the control is telling you

The auxiliary (condensate) switch connected to CONDENSATE IN/OUT has opened. The air handler shuts off the outdoor unit; normal operation resumes 30 seconds after the switch closes again.

Applies to: ComfortBridge communicating air handlers AVPTC**14 (B* revision board) and MBVC1201/1601/2001 modular blowers

Likely causes

• Blocked drain pan, trap or drain line
• Faulty or mis-wired float switch

Test and repair steps

1. Clear the drain pan, trap and drain line; check slope and venting of the drain.
2. Check the float switch and its wiring (normally closed, opens on high water).
3. After clearing, confirm the switch closes; the outdoor unit restarts about 30 s later.
