Question Heil Control Board Part number

Where is it? There is a stick on bar code on the a/c-heating computer control board, but is this the right number? Do I look for something printed physically on the board itself?

A/C -heating guys are here fixing the unit and I'm trying to save some money finding a control board somewhere else. Anyone with resources?

model of the unit: n8mpn075b12b1

Printed on the control board:
cepl130590-01
cebd430590-07a

printed on bar code sticker on board:
hk42fz0184505

Thanks!

Let the contractor install a new board. It won't cost much more and if the problem is not corrected they have to eat their mistake.

hk42fz018 - used a partial and found the board online.

Saving over $500 combined labor and savings on the board itself. Going to install it myself and dry everything off. Only reason the board went out was because of water that dripped down the wires leading to it. Otherwise it was dry. Gonna seal where the wires pull through with silicone so this won't happen again in the future.

I would love to let the installer put it in, but if they don't have to eat it (if they are wrong; which I don't think they are cause I watched and was part of the repairs) then I lost over $500. I could order 2 or 3 boards for that much at the cost I can get it online.

I'm happy. Thanks anyway ya'll !

Where did the water come from? Is this unit exposed to the weather?

In 3 levels from bottom to top there is: a/c blower & circuit board, plate separated heater unit above that and above that the evaporator coils also separated by a plate. Since the coils are above everything else in the unit, this is how everything got wet.

I thoroughly inspected it for water and found no water in the a/c area where the board is housed. It is an exposed circuit board in the air intake that got wet. The unit didn't have a proper air filter framing so lots of blow by dust got in it and clogged the coils completely and the blower pretty good. Filters used were the blue kind that are basically no good at all.

Having not seen water in the a/c unit, it wasn't till the a/c guys pointed out that the board got wet and I finally saw the water had come through the conduit wire pull hole that goes from the heater metal plating to the a/c metal plating below. The rest is sectioned off. When I install the board I'm going to GOB GOOP a bunch of silicone in this hole where the electrical wires are pulled through, so that if this happens in the future the water will not be able to leak down through the conduit hole to the circuit board by water drops actually flowing/following on the wires themselves that lead to the circuit board.

To me its like it was planned to fail. Its a pretty stupid design if you ask me... to have the coils ABOVE everything electric..... but its in a closet so I guess there weren't many options.
