have a brand new 140T KFA heater. doesnt produce enough pressure even with the adjuster fully adjusted. ignites and has a little fire but not enough to stay on before E1 comes up and it stops.
Doug - February 9, 2022

Hi Doug, Thank you for your question. If your heater is not building pressure and it is displaying the E1 error code, the overheat sensor has been turned on. Unplug the heater to reset it. If this does not help, there are some parts that you will need to check to see which one is causing the issue. You will need to check the fuel filter, the air hose, the pump motor, the control board and the igniter. Once you have determined the part you need, please feel free to call customer service. We are open 7 days a week and anyone will be happy to assist you. We look forward to hearing from you!

When I plug it in, it runs and it will not fire.
Travis For model number Master 135 000 multi fuel - December 18, 2023

Hello Travis, thank you for your question. It may be the Thermostat Limit Control 70-019-0100 is done and needs to be replaced. Or, the Fuse 70-027-0101 may have blown. And lastly, test the Main Pcb Assembly 70-027-0300. We hope this helps.
