buttnutt Posted February 8, 2020 Report Share Posted February 8, 2020 I just bought a 140000 btu portable kerosene garage heater. When I turned it on the first time the display would occasionally say CH in between temperatures. I can’t find anything online or in the manual. I just want to make sure that’s not telling my there’s a problem. Anyone know what CH means? Thanks. jon Quote Link to comment Share on other sites More sharing options...
Jb1009 Posted January 23, 2022 Report Share Posted January 23, 2022 Your thermostat is turned up past 99. Continuous heat. It won’t shut off with the thermostat. Quote Link to comment Share on other sites More sharing options...
