This Fenwal ignition board utilizes a zero-second pre-purge and a 15-second inter-purge cycle

Always check the label on the new motor's housing to confirm the capacitor rating before energizing the circuit

using it on high-side discharge lines will result in sensor failure

it will remain in its last position during a power outage

7 microamps is required for the 35-655910-991 ignition control to maintain the gas valve circuit

Heil Quaker ICP 1178404 TXV Valve 323613-751 This Fenwal ignition board utilizesThe Heil Quaker ICP 1178404 TXV Valve is a critical refrigeration component designed for precise refrigerant metering in 4 ton cooling systems. This thermal expansion valve maintains the ideal superheat across the evaporator coil, preventing liquid slugging and ensuring compressor longevity. Engineered for ICP HVAC replacement parts compatibility, the 1178404 utilizes a sensing bulb to monitor suction line temperature, modulating flow to match
