I have an ArcoAire central ac/heater in my attic and my hvac man determined that the fan relay is bad. We cannot find a replacement relay. This one is an Essex 24V 50/60HZ number 91 102006 31831. Can anyone help me?? The relay has 3 prongs on one side and 2 on the other side.Come on Speedball... you helped me before!!

Any serviceman worth his salt should have been able to do this for you. They never made a relay that cannot be replaced with some other relay to get the system running.

Essex,Steveco,RBM, all make relays that will work. Your service person will have to pick one that has the proper internal wiring so the prongs work out the same.
Does it look like the one on this page?

I agree with hvac1000 Its not hard to find a relay that will work. No matter how old or how new the system is.

It looks like this!
Thanks and I'm still looking for it.

Basically those type relays all look the same and the number of prongs determines exactly what it does. Depending upon the socket where it plugs in you could use a relay that had more prongs they just would not be used in the circuit.

As long as the relay has the prongs where the originals were (number stamped on relay housing) any additional prongs just will not be used. Just make sure the coil is for 24 volts control circuit.

Many years ago I only carried this relay with all the prong slots filled. If the socket did not have the slotted prong holes necessary for the relay to fit I would use a nipper and cut them off. This way I only had to have 3 of these relays in stock on each truck. One for 24 volts and 120 and 240. It worked out well and saved big bucks since we did not have to carry every configuration.

I found one! And you were right it has more prongs but it did have the ones I needed. I had to get on the phone and find a place that sells retail and it turned out to be a place I get my appliance parts at.
Thanks for the information... I have been educated!

Glad you got it going. I learn something new every day also.
