Keep a laminated copy of your specific machine's wiring diagram inside the electrical cabinet door for rapid diagnostics.

| Symptom | Likely Wiring Fault | | :--- | :--- | | Inducer never runs | No 120V to IND terminal or bad limit string. | | Spark but no pilot | Missing 24V at PV terminal. Check MV/PV common return. | | Pilot lights but no main valve | MV terminal not sending 24V. Check gas valve coil resistance (20-60 ohms). | | Lockout (no spark) | Poor ground (GND). Module requires chassis ground for spark return. | | Intermittent flame loss | Loose SENSE wire or high voltage wire routed too close to sense wire. | delcos 3100 wiring diagram
