Climatemaster tranquility 27 lockout 6 blinks overflow
Hi Group,
We have a Climatemaster tranquility 27 5 ton closed loop geo system that is locking out. We just had a new air coil installed this winter and obviously concerned we were locking out due to that failing. That’s not the issue we are locking out due to an Overflow condition(6 blinks). Then pan inside the unit is flowing perfectly fine. I suspected it was the condensate pump due to the amount of sludge in the pump. I got a new pump and I’m having the same issue. I wired up a multimeter to the overflow wires on the pump and I verified the pump kicks in before the overflow switch trips. Is there any know issues with the units exhibiting this issue. FWIW, this is the first time we’ve had this particular issue in 15 years. It did not lock out due to this at all when heating. It only seems to happen when running in stage 2.
Thanks in advance
