Customer called us out today because the thermostat was blank. Upon investigation, Troy found that the breaker was off after turning on the breaker we got a little blip of power into the thermostat, which prompted me to take a look at the wiring. The red wire seemed a little loose. We tighten that back down And the thermostat turned on afterwards I observed the thermostat go blank again. The float switch was dry the drain line was completely clear then when I saw it come back on again it raised the suspicion of perhaps a faulty thermostat. We had just put this thermostat in so it seems unlikely however it’s the only thing I can point you as a failure Because the rest of the system came on and the temperature dropped 8° while I was there within 20 minutes. I advised customer that thermostat could be faulty and to not be frustrated with it and try to poke it too hard put that if it happens again, we’ll look into replacing the thermostat.
