Pitco 3 Flashes

What does Pitco 3 Flashes mean?

Three orange flashes on the Pitco ignition module indicate a Pilot Valve Circuit Fault — a problem with the pilot (PV) solenoid circuit. A defective PV solenoid, a wiring issue, or a loose connection at the gas valve stops the module from energizing the pilot valve correctly. Diagnosis centers on confirming the module drives 24VAC to the PV terminals and that the PV coil is intact.

Symptoms

• Orange LED flashes three times, pauses, and repeats.
• Pilot valve does not energize as expected.
• Pilot fails to receive gas even though the module is calling for it.
• Missing or incorrect voltage at the PV terminals on the gas valve.

Common causes

• Pilot valve (PV) solenoid is defective.
• Wiring to the pilot valve circuit has a fault.
• Loose connection at the gas valve PV terminals.
• PV coil is open or out of specification.

Diagnostic steps

1. 01

   Measure 24VAC at the PV terminals

   With the module powered, measure for 24VAC at the PV terminals on the gas valve. Absent voltage points upstream to the module or wiring; present voltage with no pilot points to the valve.

2. 02

   Check the PV coil resistance

   Measure the pilot valve coil resistance. An open or out-of-spec coil confirms a defective PV solenoid that must be replaced.

3. 03

   Inspect the gas valve connections

   Check for loose or corroded connections at the gas valve PV terminals and reseat them to restore a solid circuit.

4. 04

   Trace the PV wiring

   Follow the pilot valve wiring from the module to the gas valve, looking for breaks or chafed insulation that could open the circuit.

When to call a professional

Call a Pitco-authorized technician if 3 Flashes persists after confirming 24VAC at the PV terminals and checking the coil and wiring. Gas valve and pilot solenoid work must be done by a technician trained to handle the gas system safely, verify the valve operation, and replace the gas valve or pilot solenoid to the correct specification.
