Emerson 57T01-843 Blower Time Delay Relay

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.

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

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

Purshased two so I would have a backup, just in case. Perfect fit and easy to install!

direct replacement no issues.

This works great. I have A/C again. This fit my Trane air handler perfectly.

Works like a charm and saved me a ton of money. Thanks!

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.

Delivered in good condition and performed as expected.

My fan(only) would not stop running until this was replaced. Direct replacement for a TRANE TWG018A140B1.
