Emerson 57T01-843 Blower Time Delay Relay

Good part

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

Exact same part with a different number. Mine was RLY02807. This part has been replaced before on this unit by an HVAC company so I dont know what the OEM part number was. 98 Vintage American Standard heat pump. Symptom is usually the indoor fan running constantly but this time the fan would intermittently work. This is very bad for the outdoor units compressor. Not as bad as the outdoor blower fan not blowing but almost. Luckily I caught it in time and its all working well now.

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

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

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.

As far as I can tell, this is the original. Onli 1-2 capacitors have different colors (does not affect performance). Otherwise, exactly the same part

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

I used it with a 1/2 hp blower motor to replace a terrible multi speed motor!

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