Heil Quaker ICP 1398445 Heat Sequencer
The Heil Quaker ICP 1398445 Heat Sequencer is a critical double-pole single-throw (DPST) control designed for 24V residential and commercial electric furnaces. As a veteran tech, you know that staged activation of heating elements is non-negotiable to prevent massive inrush current from tripping the main breaker. This 24V heat sequencer manages the timing of the resistive load, ensuring a smooth ramp-up of the heating banks. Built for high-duty cycles, the ICP 1398445 provides the necessary delay-on and delay-off functions required to protect the blower motor and transformer from electrical stress. Whether you are performing a 1-to-1 replacement or cross-referencing for an older Heil Quaker heating unit, this HVAC sequencer delivers reliable bimetal switch performance to maintain consistent discharge air temperatures and system safety.
Key Benefits for the Contractor- Precise Element Staging: Prevents electrical surges by sequencing the activation of furnace heating banks.
- DPST Configuration: Rated for 24VSA, offering a standard fit for most Heil Quaker and ICP electric furnace platforms.
- System Longevity: Reduces mechanical and electrical wear on the blower motor by managing the fan-off delay.
- OEM Compatibility: Replaces common part numbers including 1398442, ensuring a reliable mechanical fit in the control box.
How do I test if the bimetal disc in the ICP 1398445 has failed?
With a 24V call for heat at the bottom terminals (M1/M2), wait 30 to 90 seconds. Use a multimeter to check for continuity across the high-voltage load terminals. If the sequencer is hot to the touch but the contacts remain open, the internal bimetal disc is likely fatigued or burnt out.
What causes a heat sequencer to get stuck in the closed position?
Contacts often weld shut due to excessive amp draw or pitting from long-term arcing. If the blower and heating elements continue to run after the thermostat is satisfied, the sequencer is compromised and must be replaced to prevent an overheat condition.
Can I use this 1398445 sequencer to replace a single-pole unit?
While technically possible in some circuits, you should always match the pole configuration (DPST vs SPST) defined by the manufacturer?s wiring diagram to ensure all heating stages and the fan interlock function correctly.
