{"start":"ift_start","steps":{"ift_start":{"title":"IntelliFire Touch Troubleshooting","question":"What problem are you having with this IntelliFire Touch system?","help":"IntelliFire Touch uses an ECM control module, RF module, RC400 or RC150 wireless control, IPI pilot assembly, gas valve, and optional ACM, blower, lights, or power vent. Choose the symptom that best matches the fireplace behavior.","professionalHelp":"This guide involves gas, ignition, electrical, remote pairing, and live-voltage diagnosis. If you are not qualified to service gas appliances, stop and request professional help.","showContactForm":true,"stop":false,"options":[{"text":"Pilot will not light — no noise or spark","next":"ift_no_noise_no_spark","pathText":"No noise or spark","showContactForm":true},{"text":"Module clicks but there is no spark","next":"ift_module_clicks_no_spark","pathText":"Module clicks but no spark","showContactForm":true},{"text":"Pilot sparks but will not light","next":"ift_spark_no_pilot","pathText":"Pilot sparks but will not light","showContactForm":true},{"text":"Pilot lights but continues sparking or locks out","next":"ift_flame_rectification","pathText":"Pilot lights but continues sparking","showContactForm":true},{"text":"Pilot lights but burner will not light","next":"ift_burner_no_light","pathText":"Pilot lights but burner will not light","showContactForm":true},{"text":"Remote, pairing, or communication issue","next":"ift_remote_pairing","pathText":"Remote or pairing issue","showContactForm":true},{"text":"Fan, lights, ACM, or accessory issue","next":"ift_acm_accessory","pathText":"Fan, lights, or accessory issue","showContactForm":true},{"text":"Power vent error","next":"ift_power_vent","pathText":"Power vent error","showContactForm":true}]},"ift_no_noise_no_spark":{"title":"No Noise or Spark","question":"The pilot will not light, and there is no noise or spark.","help":"Verify the IFT-ECM selector switch is in ON or REMOTE. Confirm 120VAC power to the junction box and confirm the AC/DC adapter is plugged into both the junction box and ECM.Measure adapter output. Normal ECM power should be approximately 5.7–6.3 VDC. If using battery backup, battery voltage should be greater than 4.2 VDC.Check the wiring harness connection at the ECM, valve harness continuity, and chassis ground. The black ground wire from the valve harness must be securely attached to the metal fireplace chassis.","professionalHelp":"Electrical power and ECM testing should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ift_module_clicks_no_spark":{"title":"Module Clicks But No Spark","question":"The module is active, but there is no spark at the pilot.","help":"Verify the white S sense wire and orange I ignitor wire are connected to the correct ECM terminals. Inspect for loose connections, damaged insulation, or shorts to chassis, pilot burner, or other metal surfaces.Verify spark gap is approximately 0.095 inch to 0.135 inch. If the ECM reports a 2 Red / 2 Green lockout, this indicates spark coil failure and the ECM should be replaced.If wiring and gap are correct but spark is absent, inspect the pilot assembly and ignitor circuit.","professionalHelp":"Ignition testing should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ift_spark_no_pilot":{"title":"Pilot Sparks But Will Not Light","question":"The pilot sparks, but the pilot flame will not light.","help":"Verify the incoming gas shutoff is open and inlet gas pressure is within the appliance rating plate requirements.If a 2 Red / 1 Green lockout is present, the pilot solenoid may not be detected. Verify the orange valve harness wire is securely connected to the pilot solenoid.Check pilot solenoid resistance. Normal pilot coil resistance is approximately 38–42 ohms. If the coil is open, shorted, or out of range, replace the gas valve. Also check continuity of the valve harness and replace the 6-pin harness if open.","professionalHelp":"Gas pressure, solenoid, and harness testing should be performed by a qualified technician.","showContactForm":true,"stop":true,"options":[]},"ift_flame_rectification":{"title":"Pilot Lights But Continues Sparking or Locks Out","question":"The pilot lights but the system continues sparking, locks out, or shows Appliance Safely Disabled.","help":"A 3 Red / 1 Green code usually indicates no ignition and/or no flame rectification. Verify the white sense lead is securely connected to the S terminal on the ECM.Check sensor wire resistance from the sense rod tip to the ECM connector. Normal resistance should be less than 1 ohm. If resistance is high, clean and polish the flame sensor with fine steel wool. If resistance remains high, replace the pilot assembly.Verify the pilot flame engulfs the flame sense rod with the glass installed. Confirm system ground, inlet pressure, and that the sense rod is not contaminated, painted, cracked, shorted, or damaged.","professionalHelp":"Flame rectification diagnosis should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]},"ift_burner_no_light":{"title":"Pilot Lights But Burner Will Not Light","question":"The pilot lights and rectifies, but the main burner does not light.","help":"Verify the green wire in the valve harness is connected to the green main valve solenoid. Check main solenoid resistance. Normal main coil resistance is approximately 58–62 ohms.If the main solenoid is open, shorted, or out of range, replace the gas valve. Verify inlet gas pressure is correct for the gas type.If flame height does not respond, verify the stepper motor harness is connected. Stepper motor coil pairs should measure approximately 4.5–5.5 ohms. If out of range, replace the stepper motor regulator assembly.","professionalHelp":"Valve solenoid and stepper motor testing should be performed by a qualified technician.","showContactForm":true,"stop":true,"options":[]},"ift_remote_pairing":{"title":"Remote, Pairing, or Communication Issue","question":"The RC400 or RC150 remote does not operate the fireplace correctly.","help":"Verify fresh batteries are installed correctly in the remote. Confirm the IFT-ECM selector switch is in REMOTE and that the ECM is powered.Verify the RF module is connected to the ECM. If the RC400 or RC150 is not paired, follow the pairing procedure. When adding an ACM, blower, lights, power vent, or additional remote, the ECM and remote must be re-paired.For RC400, check child lock, diagnostics icon, and pairing status. For RC150, verify the LED behavior and allow time for RF communication in noisy environments.","professionalHelp":"Remote pairing and RF diagnostics may require professional service.","showContactForm":true,"stop":true,"options":[]},"ift_acm_accessory":{"title":"Fan, Lights, ACM, or Accessory Issue","question":"Fan, lights, or accessory functions do not respond correctly.","help":"Verify the ACM is connected to the ECM and powered by 120VAC at the junction box. If the ACM was newly installed, the system must be re-paired.For fan or light errors, check wiring and output voltage at the ACM port with the RC400 set to the highest level. If voltage is near 120VAC and the device does not run, replace the fan or light kit. If voltage is near zero, the ACM or internal fuse may be failed.Confirm fan, light, or accessory wiring is plugged into the correct ACM port and that spade connectors are not miswired.","professionalHelp":"ACM and 120VAC accessory diagnosis should be performed by a qualified technician.","showContactForm":true,"stop":true,"options":[]},"ift_power_vent":{"title":"Power Vent Error","question":"The fireplace has a power vent error or will not complete the power vent sequence.","help":"A 5 Red / 1 Green code indicates a Power Vent error on systems equipped with an approved power vent kit. Verify the power vent harness is connected to the AUX port on the ACM and to the black and brown ECM switch wires as required.Power vent systems cannot use a wired wall switch or battery backup. After power vent installation, the RC400 or RC150 and ECM must be re-paired.Check for power vent blower operation, pressure switch closure, blocked flue, insufficient draft, overheating, or ECM selector switch in manual ON mode. On properly configured systems, RC400 should show the pre-purge timer before ignition.","professionalHelp":"Power vent diagnosis should be performed by a qualified service technician.","showContactForm":true,"stop":true,"options":[]}}}
