Emerson 57T01-843 Blower Time Delay Relay

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.

Good part

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

perfect match works great

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

direct replacement no issues.

Delivered in good condition and performed as expected.

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

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

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.
