UIB (Universal Ignitor Boards)

Q: What does the L and S mean on your UIB Ignitor boards ?
A: Large and Small.
The "S" board dimensions are : 3.25" x 4.25"
The "L" board dimensions are : 3.43" x 5.10

Q: Will a UIB S work in an appliance that uses a UIB L or an Ignitor board of equivalent size ?
A: Yes. The UIB S and UIB L are electrically identical. You might have to drill a hole to accommodate the smaller board size.

Q: I have a UIB with a spade connector in stock, but the board I want to replace has a spark plug type connector . Do I have to get a UIB with a post connector? My customer wants to leave today.
A: No! The spark plug end of the wire can be cut off and replaced with a crimp on spade connector. Some of our customers stock only the UIB's with a spade connector. We make the post models for the convenience of the service center and the "Do it yourselfer" that buys over the counter.
The spark plug connector on the spark wire, can be cut off and a female spade connector can be crimped on in it's place.

Q: Will a 12 VDC UIB Ignitor boards work in 24 VAC (Park model furnaces)?
A: No! And the 24 VAC boards will not work in the 12 VDC Furnaces.

Q: I only have a Fan Control board in stock, can I use it in a water heater?
A: NO! It is for 12 VDC furnaces only.

Q: I have an Acme Whizzbang 300 water heater (purchased by Mr. Wile E. Coyote?). Which board do I use?
A: You can use the UIB S or L with a spade or a post, whichever is convenient. Please use a cover over the board for "Hose off" protection.
All of the UIBs have the same basic circuitry. The UIB S and UIB L are electrically identical, and differ only in size. The Fan Control boards are the same as the UIB S and UIB L, with the addition of a fan control relay. The UIB 24VAC is exactly like a UIB L, but designed to work on 24 volts AC.

Q: The Ignitor board that came out of the appliance uses an external sense wire, what do I do?
A: All of the UIB's work without the need of an external sense wire.

Micro P Series Refrigerator Control Boards

Q: I have a refrigerator with an icemaker and it has something stuck on the board cover with wires coming out of it. What do I do with it?

Testers for Refrigerator Boards

Q: Do you have a tester that will test the older Dometic® refrigerator boards?
A: Yes, the D-5 tester which tests all the older AES® boards prior to the "Black box".

Q: I'm trying to troubleshoot a newer Dometic® refrigerator that uses one of the black box boards. Is there a tester that makes it easier to diagnose?
A: Yes. We make the Micro P-711 Exerciser. The P-711 Exerciser allows one person to go to the back of the refrigerator, unplug the eyebrow and the thermistor, plug in the P-711 exerciser, and check the AC, DC and Gas operation. It eliminates the need to run back and forth or use two people.

Q: Do you have a tester that will test Norcold® Power supply boards ?
A: No! As far as we know there are no testers available for Norcold® power supply boards.
