System up and running with an interesting side note ... Apparently, there are a couple internal breakers on the main board in my Climatemaster Tranquility unit. I attached a picture of the location. One of the breakers was tripped due to the failing pump on my system. Interesting that the pumps will power on - and the system sounded normal to me, but with a tripped breaker the pumps were not getting full power. *** side note *** I had already picked up a spare pump for my system, again the lower pressure B&D QT system. The (spare) pump was sitting for about 2 1/2 years since the last pump replacement. And have now been told that these pumps need energized every 2 or so years to keep the main capacitor fully charged and functioning. Well this spare pump will not turn on when I applied some power. So much for being pro-active and having a spare water pump here for emergency.... Does anyone know if there is a way to re-energize this capacitor - may be easy enough to source one as well. Thanks for any feedback - and keep check your furnace side breakers when replacing a B&D pump ! Don in Ohio
