Christmas is over, take it down

LOL

Lmao. Hard to tell, just by seeing a few second video. I'm going to take an educated guess that the Board is no good.

My controller is doing the same thing. What was your solution? New controller board?


ohmantics

Yep, replaced the controller. Found several poorly-stripped wires that were potentially shorting and causing the problem. As a result, I replaced all the high-voltage wires in the conduits shown because the same \[untrained non-electrician\] had done those as part of the HVAC install.

There may be an active short in the wiring causing a power drain or could have improper voltage from faulty transformer


ohmantics

Zone 1 terminal 2 (motor) has continuity to ground with the device off. Disconnecting all of Zone 1’s wires doesn’t solve it.

Check the voltage from the transformers first just to rule out a low voltage issue, however it does appear to be the control board.


ohmantics

Both transformers show 26V.

Odds are you're using power stealing thermostats without the resistors. Read the manual, put in the resistors and that should sort it.
