Repair & Advice
This control board is attached to back of the plastic cover on the right side (behind door)
The top vent cover must be removed first. There are two screws along the top edge.
Then one that goes from the top vent cover into the control board cover.
Once the screws are removed, there are two tabs at the bottom of the top vent cover
Gently squeeze the cover at the tabs and pry upward.
Once it is remove, push up on the control board cover to unlatch and pull out.
Take a picture or take note on which wires go on which terminal.
All the small wires have unique connectors, but the individual wires that go to the relays are just spade lug and can be re-assembled incorrectly.
When disconnecting spade lug wires: They are very tight. DO NOT pull on the wires! Use some needle nose pliers to pull on the lug with a rocking motion.
It's very easy to pull the wire out of the lug and if you're not an electronic tech with a soldering iron, you're in trouble.
There's a ground strap that is connected with a screw and then there is one (or two) screws that hold the board to the cover.
Like all consumer products it was designed to be assembled easily, with no regard to disassembly. It's very easy to break the plastic or pull a wire out of it's connector.
If you're not reasonably mechanically / electrically skilled then bump up my difficulty level rating.
