Have a Master 70,000 BTU kerosene heater that we use good grade diesel in, have used for 2 years no problem, will run all day but doesn't want to start in AM, starts for a few seconds and then shuts down and red light on switch blinks. Let it cycle through running with no flame until it quits blowing, then will run through another cycle when switch is shut off. Sometimes when restarted it will work but now more and more likely not start. Have done no maintenance on it during the 2 years I have had it. Any suggestions?
