Espar Bunk Heater Yearly Preventative Maintenance

what if you change the glow plug and screen and still no heat. what could be the problem?

 

That's interesting as a tech @ TK of Denver told me opposite couple of years ago. He told me also to run kerosene through it and that will make it run the best as these bunk heaters are designed to run on kerosene.

 

That's what I was told also.

 

at the end of season, I take a 1 gal jug of kerosene and stick the feed line into that and run it wide open for 15-20 min. got an Espar in the truck for 7 years now, no replacement parts yet

 

I just bought a 2015 T660 today and the heater control panel says “heater enabled maintenance required”

If I clean the glow plug and screen will it need to be reset or will it recognize works been done?

 

Try this

 

Try resetting your hours on heater. I was having the same issues as you.

 

Thank You Sir

 

has anyone had a "flame lost" error happen before? In January in Wyoming this year, it was super windy (like it always is, rocking the truck around while parked windy) and i was parked on the edge spot at a truck stop (taking all the wind). Halfway through the night I woke up cold af and the heater was displaying "flame lost" error. Like it got blown out like a candle. It did it once more after i started it again, and then i put it up to 95 degrees so it wouldn't ever stop blowing hard, that worked to keep it on for the rest of the night. how do you "lose flame" on a glow plug? it's not like it's a pilot light in there...

 

Probably carbon fouled. Does it smoke on start up? You might not notice it until you get out of the truck and see cloud of smoke billowing from under your sleeper
