Can This Be Saved? 550 EC Tankless Water Heater Burnt Board Repair

Is your Precision Temp 550-EC dead after an electrical short? Don't throw away that $300 circuit board yet! In this video, I troubleshoot and repair a Precision Temp 9049F v.08 control board from a 550-EC Propane Tankless Water Heater. The owner accidentally shorted the system, which vaporized a high-current power trace on the back of the PCB. I’ll walk you through: The Diagnosis: Identifying the burnt "highway" trace and checking for carbon tracking. The Cleanup: Why you MUST clean away the burnt fiberglass to prevent future shorts. The Repair: Using a high-gauge copper jumper wire to restore the 12V DC path. The Bench Test: Using a multimeter to verify the 7805BT voltage regulator is still putting out 5V to the main processor. Safety Warning: Working with gas appliances and electrical circuits involves risk. This video is for educational purposes. Always shut off propane and power before servicing your RV or home water heater. #RVRepair #PrecisionTemp #TanklessWaterHeater #CircuitBoardRepair #DIY #ElectronicsRepair #OffGridLiving
