using Delta 3 receiver and transmitter set with an external 24 volt power supply

But the only remote I have left is falling apart, and is no longer dependable, particularly in very hot or very cold weather. The transmitter/receiver system is the old analog type - no digital codes at all, just the specification of "carrier frequency" and "modulation frequency", and the receiver is powered by 24VAC provided from the main chassis. In fact, it appears that the receiver actuates the opener mechanism by at least partially shorting out its own power supply temporarily. I have been unable to find any direct replacements for either the transmitter or the receiver. In fact, I don't really see any total replacements for the transmitter/receiver system that would operate using the 24VAC power supply. Does anybody have any suggestions for what to do? I'd like to avoid having to replace the entire opener. using the Delta 3 receiver wired with an external 24 volt power supply should fix the problem. your old sears operator has 2 terminals that when shorted actuate operator. connect terminal 1 on the Delta receiver to the ground terminal on operator and terminal 2 on the receiver to the 2nd terminal on the operator. connect the external 24 volt power supply conductors to terminal 2 and 3 respectively on the Delta. set receiver and transmitter switches to match. check operation. -- |

I would replace the entire opener, they arent expensive and newer ones are much safer, with auto reverse and detectors f anything is in the way...
