4. Setup and Installation
Installation of the ignition control module requires electrical knowledge and should be performed by a qualified technician. Refer to the heat pump's service manual for specific wiring diagrams and mounting instructions.
4.1. Pre-Installation Steps
- Ensure the heat pump unit is completely powered off at the main breaker.
- Verify that the replacement module is the correct part number (Raypak Kit # 007374F).
- Gather all necessary tools, including screwdrivers, wire strippers, and a multimeter.
4.2. Installation Procedure
- Carefully remove the existing ignition control module, noting all wire connections. It is recommended to take photos of the existing wiring before disconnection.
- Mount the new Raypak Ignition Control Module in the designated location using the provided screws.
- Connect all wires to the appropriate terminals on the new module. Refer to the wiring diagram in your heat pump's service manual.
- Ensure all connections are tight and secure. Use the provided wire nuts and zip ties for organization and safety.
- Once all wiring is complete, double-check all connections for correctness and security.
- Restore power to the heat pump unit.
5. Operating Instructions
The Raypak Ignition Control Module operates automatically as part of the heat pump's control system. Once installed and powered, it will initiate the ignition sequence when a call for heat is detected.
- Ignition Sequence: Upon a call for heat, the module will begin a pre-purge cycle, followed by igniter activation and gas valve opening.
- Flame Monitoring: The module continuously monitors the flame presence. If the flame is lost during operation, the module will attempt to re-ignite (recycle on loss of flame).
- Safety Lockout: If ignition fails after multiple attempts, the module will enter a safety lockout mode, indicated by a diagnostic code.
Refer to your heat pump's main user manual for overall system operation and temperature settings.
6. Maintenance
The Raypak Ignition Control Module is designed for reliable, long-term operation with minimal maintenance. However, periodic inspection is recommended as part of your heat pump's overall maintenance schedule.
- Visual Inspection: Annually inspect the module and its wiring for any signs of damage, corrosion, or loose connections.
- Cleaning: Keep the module free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Do not use liquid cleaners.
- Professional Check: It is recommended to have a qualified technician inspect the entire heat pump system, including the ignition control, annually.
7. Troubleshooting
The FENWAL label on the control module provides diagnostic status codes to assist in troubleshooting. Observe the LED indicator on the module and refer to the table below:
| Code | Condition |
|---|---|
| ON | System OK - no faults present |
| OFF | Possible control fault - check power |
| 1 Flash | Low air - brief flashing normal on startup |
| 2 Flashes | Flame W/O Call for Heat - system fault |
| 3 Flashes | Ignition Lockout - TH-off to reset |
| 4 Flashes | Igniter Failure - check amp draw |
| 5 Flashes | Low 24 VAC - check control supply voltage |
| 6 Flashes | Internal Fault - replace control |
If troubleshooting steps do not resolve the issue, contact a qualified service technician.
