The continuing saga of Jim's Dometic 1402....
So yesterday I finally got my new defrost heater and got to work.
It had been frozen up for a good week, and was a mess inside.

the cooling fin unit is the freezer was a solid block of ice.

And here's the cause of the error 13. The tail on the "freezer drain heater" is kinda destroyed. Now again, I did this, taking the unit apart repeatedly to clear out the ice.

Parts is parts!

This time I took everything out, including the lower ducting, which then allowed the freezer fan to be removed.
I tested the fan in service mode 12 and it did turn on.I put everything back together. I wired a computer fan in parallel with the existing fan, and verified in test 12 that both fans ran. I attached the second fan below the icemaker, blowing in toward the cooling fins. (I had previously confirmed that the factory fan "Sucks" the air out of the cooling fins and blows it down thru the lower duct, air enters thru the bottom of the cooling fin block. I still need to tidy up the wires.

So far so good, no more error 13.
This morning found the fridge at 35, the freezer at 19. (down from 45 and "High") I'm sure it will be fully cold by the end of the day. But will it defrost?
