Raypak IGN CTRL

What does Raypak IGN CTRL mean?

Per the Error Display table, IGN CTRL indicates an internal control fault with the instruction to reset power and replace the control. The PIM has detected an internal failure it cannot recover from automatically. The corresponding PIM guidance shows a steady red LED for internal control failure and directs performing a power and system reset, then replacing the PIM if the fault remains.

Symptoms

• IGN CTRL shown as the active error on the display
• Red LED steady ON on the PIM (internal control failure)
• Heater does not operate
• Fault persists after a power reset

Common causes

• Internal PIM control failure
• Power-quality event affecting the control
• Failed internal control component
• Control needing replacement per the manual

Diagnostic steps

1. 01

   Reset power to the control

   Per the manual, perform a power and system reset to attempt to clear the internal control fault.

2. 02

   Confirm the LED state

   Check whether the steady red internal-control-failure LED clears after the reset.

3. 03

   Replace the PIM if the fault remains

   Per the PIM guidance, if the fault remains after the reset, replace the PIM/control.

4. 04

   Verify wiring before re-power

   Before re-powering, the manual cautions that wiring errors cause improper and dangerous operation; verify proper wiring per the wiring diagram.

5. 05

   Observe operation

   After replacement, confirm the heater operates normally without the internal control fault returning.

When to call a professional

Replacing the control module is a parts-level repair on a unit with gas and live electrical connections, and the manual warns that wiring errors can cause dangerous operation. Because this fault calls for replacing the control once a reset fails, and correct configuration and wiring are critical, have a qualified Raypak service technician perform the diagnosis and replacement rather than attempting it without manufacturer support.
