Dinosaur Electronics TDR Time Delay Relay

This time relay switch works!!

Works great

eselent, i like it

I used this on a Suburban NT 20 SE furnace in my camper to fix the problem of the fan powering on spontaneously, having first replaced the thermostat. However I am very grateful for Richard Pomaibo's review here since this does not replace a similar part on this furnace, I think that is part of the circuit board. So I had to locate the various leads as described by Richard and connect them to the new unit, which included replacing the crimped connector on the hot lead which was the wrong size. Once wired correctly this item worked perfectly. It would probably have been easier to replace the circuit board in the furnace, but that is twice the price of this unit. And you can buy a complete new furnace on Amazon for less than $400 which would be another option. So now the furnace fan comes on for a few seconds before ignition, and stays on for about two minutes after the furnace switches off, and no more spontaneous switching on of the fan.

Relay worked and everything function but the timer would not. Shipping was incredibly slow. They created a label then wait 5 days to actually put it in the mail.

The relay is probably good, But it's to big to fit where it needs to go. I have been trying to figure out how to return it. Can you help me?

They only last for a year seems as much as you pay for the relay should atleast last for 5 years. Keeps your motor running when your temp is up.

I have blown 2 of these relays, I might buy one more. One person said on here that the wiring is all messed up and they were right. The positive and negative don't go to their designated terminals, that hoe I bleed the last 2. Gonna take a different approach and see if any of the other components need replaced.
