thermo king apu En9

I have a thermocline evolution on my Pete. It was working fine all night, I shut it down to check the oil this morning & now it won't start up, the fan won't even start. I was told there's a reset button, but can't locate it.
Any ideas?

 

Reset button worked for me! Yay thanks fellows.

 

If the reset button doesn't help then pop the APU cover and unplug and replug the wiring for every sensor you can find.

 

After doing a Regen, APU will not start. En9 light shows on heads up display. Reset button under the bunk has not tripped and will not reset. On off switch at motor has been turned off and on several time in an attempt to restart but still not starting. Fan under bunk will run for a few seconds but starter will not engage...any ideas please

 

Same problem any help?

 

I was running only the fan, didn't need heat or ac, and it worked fine. Then suddenly the unit started up and then shut off throwing En9 code. Let it sit for several hours and tried to turn just the fan back on. On the fan comes on, not the unit itself but then the fan immediately cuts off and throws the En9 code again. Does anyone have any ideas? Thanks

 

You have to reset the breaker under the bunk. It will be on the side of the black plastic box. You may also have to turn off the display unit and then back on.
