Mr. Bryan Pike was very helpful in providing a wiring diagram for installing the 4243 Motor Board Bridge.

Motor board bridge for Aprilaire 760 by Andy E. (Cleveland Oh US)
Couldn't believe the difference this repair part made. The old one had cracks which made the entire humidifier noisy. (After installing the new motorboard bridge, the humidifier was then so quiet in operation, I thought the fan motor had failed!) Overall, I'm completely satisfied with the part, the service, and availability of repair parts from Aprilaire.com.

Solid, perfect replacement for the cracked motor bridge in my 10 year old model 700. Very happy to be able to repair my unit with replacement parts, rather than paying a lot more to replace the unit. Love this site!

The part was the correct fit. Your gridwork pictures were a big help.

Motot Board Bridge by Charles E Kenyon (Brightwood Vi US)
The motor board bridge was broken when an earthquake shook the motor and fan unit off of the base and it fell six feet to floor. The replacement is a perfect fit in this ten year old unit. I am very pleased with the quality of construction of my Aprilaire unit.
