Emerson 90-370 Fan Relay Rbm Type 184 Heavy-Duty Enclosed

So worth the $10 gamble to see if it fixes your problem, so you dont have to pay an HVAC company thousands of dollars to replace your perfectly working HVAC system because its "too old to be bothered with". With the right amount of maintenance, anything can last, this part made that possible.

Worked as imagined

Furnace would not run or was intermittent at best. installed this relay, furnace working perfectly again.

Feb 2021: Says made in USA, but isn't. Else, exactly as advertised and plugs in and works. 4 stars.Dec 2021: failed in the on position after 10 months. Removing power and allowing it to cool allowed the contacts to release. Post mortem investigation- Contacts show signs of welding, more wear than would be expected given the time and number of cycles. Design could be better, the spring which balances the contacts also allows one side to weld itself to the opposing pad. These are rated 100,000 cycles MTBF under load per the manufacturer's website. Down a few stars due to life cycle issues. Still has value due to low cost and fast lead time.We will see if they honor the 1 year warranty. Else, I'm looking for a more robustly made 90-370 relay.

I finally got fed up with having to go out and bang on the furnace to either get the aux fan to shut off, or to go on, and ordered this replacement for my Coleman Presidential furnace. It fit right in place, clipped in, and worked perfectly.This unit comes with both normally-open and normally-closed contacts, so it's pretty versatile and should work in a variety of situations where 24VAC is the trigger voltage. If you use this in a furnace, be sure you understand what you're doing and connect it to the correct ones.

Works great; but note this is made in China, not in the USA like description says...

I always had a hard time finding this style.

Fixed my old furnace. Working great now and no expensive service call for a $10.00 part.

Only had this unit since October 2019. Installed to connect my gas fireplace hooked up to a Nest thermostat. Worked perfectly for 4 months. Now just keeps clicking, and does not work.

I bought 2 for fans i wanted to move air around my basement and my garage. Used the gas valve feed from furnace controllers. Functioning as designed. The tabs on the ends make it easy to mount.

Works as advertised could use a schematic included

This 24vac relay worked perfectly with our new Google Nest 3rd generation thermostat to power on our gas fire place.

Did the job so I am satisfied with the product.
