What causes 'Heater 2 Gas Vapor Temp Hi-Limit' error on GSi Touch terminals?
- LLisa RiceSep 4, 2025
The 'Heater 2 Gas Vapor Temp Hi-Limit' error on your GSi Touch terminals indicates that the LP gas vapor temperature sensor located in the gas pipe downstream from the vaporizer coil on fan and heater #2 has opened, meaning the vaporizer coil is running too hot. Adjust the vaporizer by loosening the bolt and moving it away from the flame. The sensor automatically resets itself.
