Emerson 57T01-843 Blower Time Delay Relay

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

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

Works great for the price this is a must buy!!

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

Part was exactly what we needed and our air conditioner is running like new again because of it!

Delivered in good condition and performed as expected.

This is a good price on this board and Im not sure Ive been able to find a better price anywhere. I seem to go through one of these boards about every three years. Uncertain if my HVAC system is the cause, or if the reliability of this board is the issue. In any case, I keep a spare on hand now.

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

Works just as it should. Very happy with this purchase!

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.
