The following service procedures are provided as a general guide. Follow appliance manufacturer’s service instructions if available. 2. On lockout and retry models, meter readings between gas control and ignition module must be taken within the trial for ignition period. Once the ignition module shuts off, lockout models must be reset through the key buttons and display. On retry models, wait for retry or reset at the thermostat. 3. If any component does not function properly, make sure it is correctly installed and wired before replacing it. 4. The ignition module cannot be repaired. If it malfunctions, it must be replaced. 5. Only trained, experienced service technicians should service ignition systems. Perform the checkout as the first step in troubleshooting. Then check the appropriate troubleshooting guide and the schematic diagram to pinpoint the cause of the problem. If troubleshooting indicates an ignition problem, see Ignition System Checks below to isolate and correct the problem. Following troubleshooting, perform the checkout procedure again to be sure system is operating normally. Intermittent Pilot Ignition System Checks STEP 1: Check ignition cable. Make sure: • Ignition cable does not run in contact with any metal surfaces. • Ignition cable is no more than 36 in. [0.9 m] long. • Connections to the ignition module and to the igniter or igniter-sensor are clean and tight. • Ignition cable provides good electrical continuity. STEP 2: Check ignition system grounding. Nuisance shutdowns are often caused by a poor or erratic ground. • A common ground, usually supplied by the pilot burner bracket, is required for the module and the pilot burner/ igniter sensor. — Check for good metal-to-metal contact between the pilot burner bracket and the main burner. — Check the ground lead from the GND(BURNER) terminal on the module to the pilot burner. Make sure connections are clean and tight. If the wire is damaged or deteriorated, replace it with No. 14-18 gauge, moisture-resistant, thermoplastic insulated wire with 105° C [221° F] minimum rating. —Check the ceramic flame rod insulator for cracks or evidence of exposure to extreme heat, which can permit leakage to ground. Replace pilot burner/igniter-sensor and pro...
