Espar D2 Won’t come on, fuses are all good, what can it be?

So my bunk heater stopped working completely, the fuel pump won’t click, the blower fan won’t run. I can’t get any codes since it’s hooked up to my tripac evolution which has no display, I don’t know where to even start, any help would be appreciated

 

Looked at all the fuses and they all looked fine, I wonder if theirs a fuse on the controller knob where u turn the ac/heat on

 

The tripac works, ac works and the tripac does charge the batteries, but when I switch it to heat I get nothing, no fuel pump click and the blower fan doesn’t spin either, it’s a tripac evolution btw

 

The controller works, I do have the tripac program in my laptop and theirs no codes unfortunately, I even tried the heat service test thru the laptop and it doesn’t come on either, all the fuses are good even the ones in the battery box, I wonder if the ecu on Espar is fried, is their a way to check the ecu?

 

I haven’t checked the fuel pump yet, but even if the pump was bad, wouldn’t the blower fan come on at least then turn of once the system detects a problem
