My Utica boiler is throwing a code 58, A/C line frequency error code. Unit is about 4 years old and has been fine since the install. It throws this code when it fires the igniter. (Electric spark ignition) Tech support wont help as Im just a home owner. But they did tell me the control module is sensitive to ground issues. Been through the entire circuit from panel to power hookup on the unit. Retightened any wire nuts.
No change.
