How to Manage OEM Boards and Cores on Appliance Vans

Control boards are the high-dollar items most likely to “be on a van somewhere.” Treat them like cash with a barcode.

A board needs a home and a name

Part number from the vendor, not a nickname. Photo of the connector side. Min stock of zero or one on the van unless you replace that board every week. Everything else waits in the shop.

If two brands share a look-alike board, they still get two SKUs. Mixing them is how you eat a restocking fee and a second trip.

Checkout for the expensive ones

When a diagnosed job needs a $280 board, transfer it to the van that morning. If the job cancels, transfer it back the same day. Do not let “I’ll use it later” become a three-week vacation for the part.

Serialized checkout is even better for boards you track by serial. The history should show who had it last. That ends the parking-lot search.

Core tags on the same day

Bag the bad board, tag the job number, scan it as a core on that van. Friday is core run day. No tag, no credit. Make that as automatic as emptying the trash.

Vendors expire core credits. A van that is a core museum is a cash-flow problem, not a storage solution.

Warranty boards are still a count

Manufacturer warranty does not mean the van count stays the same. The good board left. The bad board may go to the OEM. Scan both motions. Otherwise you will reorder a board you already used and cannot prove.

Keep a simple reason code in the job notes: billed, warranty, or core. The office should not guess from a text that says “fixed fridge.”

Train the habit on the ten most expensive SKUs first

Do not start with screws. Start with boards, pumps, and sealed-system parts. When techs see those stay accurate, they believe the system. Then expand to valves and ignitors.

FleetStock’s technician phone view is built for that habit: scan, job number, use or return. No office sidebar in the customer’s kitchen.

FAQ

Should every board be serialized?

Serialize the ones you warranty or that cost enough to hurt. Quantity tracking is enough for cheap repeaters.

What if the vendor will not take the core?

Write it off from the van with a reason. Do not leave it in the count as sellable stock.

Can office staff see who has a board?

Yes — transfer and asset history show the van and the user.
