Cold out today because unit wasn’t cooling Upon further evaluation, I found a tiny bit of water in the float switch. I was able to clear the water and clear the drain line. The drain line wasn’t even backed up. It was completely clear and I flushed a bunch of hot water down there to be safe. After I cleared the water, the unit still wouldn’t kick on, and I thought one of the float switches was bad. I bypassed them and the unit still didn’t come on. I managed to get the unit to come back on. I had to replace one of the flow switches because I had cut the wire. I blew a fuse at one point replaced the fuse. Unit is up and operating at this time in the drain line is completely clear.
