How to Fix / Troubleshooting
Safety: Turn off power before touching the control board or wiring.
Steps:
- Power cycle: Turn off the breaker for 30 seconds, then restore power to see if the error clears.
- Inspect control board: Remove the control panel cover and visually inspect the ignition control board for burn marks, swollen components, or corrosion.
- Check connectors: Reseat all multi-pin connectors to the board, ensuring they are fully engaged and keyed correctly.
- Verify proper grounding: Ensure the heater chassis is properly grounded; loose grounds can cause erratic control behavior.
If E13 returns after basic checks, the ignition control module likely needs replacement. This should be done by a technician to ensure correct configuration and safe operation.
