ICP Transformer for WAHL244C1 — 40VA 208/230V to 24V | Ships Today

Overview

This OEM control transformer (part number 1172028) supplies the 24V control power for your ICP WAHL244C1 system. It steps line voltage of 208/230V down to the 24V secondary that operates the thermostat, relays, and control board. Rated at 40VA, it provides reliable low-voltage power to the entire control circuit. A failed transformer leaves the system completely unresponsive — no thermostat display, no blower, no call for heat or cool — even when line power is present. A burnt odor, a blown internal fuse, or no voltage at the secondary terminals all point to a shorted or burned-out transformer.
