Emerson 57T01-843 Blower Time Delay Relay

Product work as advertised and easy to replace , exactly like the broken one

Looks different then the original but has all the same connection works great.

The product is great. Package want sealed all the way. First time this has happened Thank you for delivering great product!!

direct replacement no issues.

This Timer board worked perfect in my daughters Trane Air Handler. The fan motor wouldnt start and she had already called a HVAC company and was charged $200 to replace a $10 start capacitor which didnt fix it. If she had called them again Im sure it would have cost $250 or more (Thats $450 dollars for a job that should have cost less that $100 with labor). I changed this in about 10 minutes for only $21.99 and she was up and running. I only wish one day delivery was available on this item.

I suspected I had a bad relay when my blower fan would either shut off immediately after reaching the thermostat setpoint, or sometimes it would never shut off unless I opened the breaker. I verified that this relay was a replacement for the original in my 16 yr. old Trane unit. It was slightly different than the original, but the terminal designations made the swap simple. My unit now runs like its supposed to, at a fraction of the cost of having an AC company do the work.

My Air Handler twv025b140a1 blow motor was turning on and off continuously. This fixed the problem.

Direct replacement for most Trane and A/S units under 10 years old.

Worked great to upgrade an older unit to this newer relay. Included diagrams for wiring conversion to new unit. A/C fan, both heat and cool, has been running randomly (80-90% on) for years. Works as it should with delay now.

Direct replacement for 4352-F relays installed on Trane air units. Quick and easy replacement for burned out relay and for a fraction of cost quoted by local contractor who literally insisted to replace the whole Trane unit.
