Resideo S8701A1122 Ignition Module 320720-756 The AH24B020 is a lead-wired

The AH24B020 is a lead-wired model without an built-in auxiliary switch

This component is essential for maintaining proper superheat levels and preventing compressor slugging or rapid cycling by detecting precise changes in suction pressure

Most failures result from moisture intake in the diaphragm or electrical arcing at the terminals due to high resistance

Contractors will appreciate the plug-and-play wiring harness and precision-fit bulkhead

the 415-46553-02 sensor ensures the control module receives clean resistance signals

Resideo S8701A1122 Ignition Module 320720-756 The AH24B020 is a lead-wiredResideo S8701A1122 is a direct spark ignition (DSI) module designed for gas fired HVAC systems including furnaces, boilers, and rooftop units. It features a 21 second trial for ignition with lockout control, providing reliable burner sequencing and flame verification during startup. This ignition module is commonly used as a replacement control in systems experiencing ignition failure, inconsistent flame sensing, or unreliable startup sequences. The
