I have been struggling to troubleshoot the cause of my ignition fault. When the heater first failed the blower would still run. I replaced the Air Pressure switch and Hot Surface Ignitor. I did see glow on the hot surface ignitor,but my burners would not stay on for longer than 7 seconds. I had a replacement Fenwal ignition control and replaced that. No change. Frustrated, I relucantly called my Pool Service Tech.
His initial diagnosis was that the Fenwal ignition control was bad. Then he called Jandy. He bypassed the Blue/Black wire (to blower) F1/F2 and the blower worked. So he replaced the Power Distruibution Board (PDB) with a new board. This New PDB board failed to solve the issue so he told me I needed a new Fenwal Ignition Control. He removed the New PDB.
Over the weekend, I rechecked Steps 1 through 12 on the JXi Troubleshooting guide. Step 12, there is 120 between F2 and ground but the blower is still not on. The Voltage between F1 and ground (white wire) on the Blower harness is zero. When it should be 240v. Inspection of the connection/pins/undersurface of the PDB board and interface card does not show any sign of corosion/burn/damage. Ohms test of disconnected black wire/white wire on the blower harness was NOT OL. I suspect that the connector and/or wire is the culprit. Any other thoughts?
The Blower harness wiring is one piece, I do not see a replacement part for this. Do I need to replace the wiring and connector? If so please walk me through this processs.
I see that there is a capacitor in the blower, could this have anything to do with this failure? Purpose of the red/yellow and blue wires to the Blower?
