I bought a Koehring Master instant heater ( kerosene or diesel) heater years ago , never used it much but when I used it in my workshops at Stanbridge Earls and later in West Wellow , I just plugged it in and switched on and it used to run continually for as long as I wanted it , usually bursts of 10 minutes or so until I switched it off.
It stood around for years but recently when I tested it I found that it will run for about one minute , then cut out , and then start up again if still plugged in . I am not aware of a thermostat but it behaves as if there is one . Its quite old now , model B 100 E , spec 3114 GT , seriel no 1-282054 , 9 gal tank , BTU 90,000 . I took the top cover off and made a cursory examination but there was nothing obviously wrong , it fires up , runs seemingly ok but cuts out , then after about a minute ,it starts up again . Does anybody have any suggestions ?
