I am not very knowledgeable but maybe bunk heater needs cleaned. My TriPac is still pretty new 771 hours so no issues yet.

make sure nothing is in front of the blower motor intake, is it's clear and the blower runs, it's most likely the glow plug

Assuming the APU is fully operational, you don't feel hot air blowing? Did you check the blower motor, which pumps hot air into the air ducts? Check to see if there's a fuse box. Its possible the blower motor has its own fuse. Before this happened, did you plug a high-amperage appliance like a microwave, heater, or stove ?? Yes, that will trip or blow the fuse. Hopefully, yours is the type that you flip a switch or press a button to reset the fuse.
