I have an A/C air handler with a 120vac whole house electrostatic air cleaner. The air handler uses a multi-pole 40va transformer for control voltage, input is 240v, as the blower fan is also 240v. Other legs on the transformer are 208v, which is capped off, and 120v which is supposed to run the air cleaner. I have 240 volts at the transformer, I have 24v out of the secondary side. I only have 2.4vac out of the 120v leg, and 80vac out of the 208v leg! All legs ohm good removed from the unit. If I plug the 120v input and common into a 120v ac outlet, I get 208 and 240 volts at the other legs. I have traced the nuetral from the air handler back to the panel, cleaned the lugs and all is good there. I get 240 at the breaker, 240 at the service switch, and as I said 240 to the control box. The fan works fine. I just cant get 120v to the electrostat. Tried it with 2 transformers, no joy. Any thoughts?
