Let's start with the basics. Are you sure you are getting the correct power to the unit? If 120 volts, use meter and check across power and neutral, not power and ground. If correct power is present, check the defrost timeclock for proper operation. If bad and stuck in the defrost cycle, nothing will work except for the defrost heaters. It should terminate defrost cycle and return to the freeze cycle, but if terminator is bad, it will just sit in defrost. Start here and get back to me and we can continue.

Engel fridge trips power when mains power turned on. Fridge set in off position.

There is a dead short line to line or line to ground. The dead short can be detected with a electric continuity tester connected across the load side of the mains (power shut off) and opening covers and inspecting the wiring.

Bad smell from fridge (not mouldy food)?

There is no danger if there is a leak, but the refrigerator will quit cooling. I suspect perhaps you have a dead something underneath or behind the refrigerator. I hope this helps... but I also suspect you have cleared the problem by now.

Auto defrost wont work check heater all good

Not very familiar with fisher however I have worked on a few for my friends. Usually the only other two things in a system would be your defrost termination and defrost timer. The more likely and cheaper of the two would be the termination which would be located on the top of the evaporator coils. You can usally visually inspect these and if they are bad they look (popped out). Lastly and most unlikely would be the defrost control. Usually if the control is bad the unit will be completely dead. Let me know if you need more help past the termination.

Small frigidaire with very small freezer completely fill with frost

Most of the smaller freezers are not self de-frosting, Im not certain about the one you have but usually the only way is to unplug them and let them thaw out for a few hours. Make sure to put towels down to absorb the water or you may have a mess.
