So, I recently bought a used (low hours) carrier comfortpro apu with the bunk blower for my truck. The generator works fine but when I try to use the blower(HVAC) for a/c or heat inside my truck it doesn't work. No air gets blown but the generator still works. On the driver control panel (the screen to control it) it says there are no faults but the temp is usually higher than it is(For example, if its 25°C inside the truck, it says its 35°C on the screen). I called Reefer Sales(Carrier dealer in my area) and they said it might be a temp sensor issue causing it not to blow air and I might need to replace the bunk unit. I was wondering if anybody else had this problem and how they managed to fix. Can I just buy a new temp sensor and repair or do I need to a new bunk unit? Just exhausting all my avenues of help to see if there's any possible ways of fixing it.
