Chang d electric heat strip out and breaker and checked system operation - everything looks and runs great!

Found damper number 22 bedroom area not opening when 24 V is removed. I replaced this damper and checked it several times to make sure it opened and closed zone three actuator was replaced because it was getting hung up on opening as well. Tested zone three open and closed like it’s supposed to. These two are under warranty. When I turn the breaker that’s on the unit back on it would not power back up on closer inspection I found condensation on it and we will have to replace either the breaker or the heat strip. This will also be under warranty. Right now I have the wires wire nut together so if if we need to turn the power off. We have to turn it off at the main breaker

Was informed heat strips didn’t work. Turned on emergency heat at thermostat. Tested amp draw on both 5KW sections both drawing 20 A switched it off at the thermostat several times and retested with the same results. Took a temperature difference on the heat strips 20°. Tested heat pump and auxiliary heat at the same time. Auxiliary heat doesn’t come out with the heat pump with a 10° setpoint. Thermostat should be turning on the auxiliary heat at 2° below set point or more this thermostat needs to be replaced
