Crown RM 6000:
Freezer heaters not working

customer states that the truck quits working after about 30min in the freezer, and once it thaws it fine. I have B+ going to the F/C distribution board but nothing coming out to the heater resistors, the relay isn't closing when key is turned to the 'on' position, checked diode on F/C distribution board and found it open, anyone else had a similar issue? Not 100% sure this is gonna fix it but. ordered one.

Check thermistors are working, heaters will not come on until they are cold, disconnect wiring at them and short them together to turn on circuit path

Did any of the heater wires get pinched in the multitask handle? Should have blown a fuse first
