Overview
This OEM 24-volt control transformer (part number 1053004) supplies low-voltage power to the control circuit of your ICP ZAEB015CLA1 package unit. The transformer steps line voltage down to a stable 24V signal that energizes the thermostat, contactor coil, relays, and safety controls. Rated at 40VA, it delivers enough capacity to drive multiple control devices simultaneously without overheating. When a transformer fails, the entire low-voltage control system goes dead — the thermostat screen may go blank, the contactor will not pull in, and the unit produces no heating or cooling even though line power is present. A buzzing transformer, a tripped low-voltage fuse, or a melted/discolored housing are all classic signs the original component has shorted or burned out.

- Access — Remove the control-panel service cover.
- Document — Photograph every primary and secondary wire connection before disconnecting.
- Remove — Label and disconnect the leads, then unbolt the failed transformer from the mounting bracket.
- Install — Mount the new transformer, matching primary taps to your supply voltage, and reconnect each lead per your photo.
- Test — Restore power and confirm a steady 24V reading across the secondary terminals.
