Furnace Blower Replacement

Hello Helpers,

I think my 20-years furnace blower is going out. The model is GE 5KCP39LG V569BS, which is a 0.5 HP 1075 rpm with capacitor starter. Since this is no longer on market, I wonder if there is any suggestion as to which made and model is a direct replacement? And where to get it? I live in Central Ohio. Thanks for your suggestions.

In the last 5 years, when the blower is on during Winter, the thermostat would intermittently shut off for 1 minute, then come back on. During thermostat shut off and before back to operation, the blower and furnace would continue to run. After thermostat turns back on and complete initialization, the furnace and blower blower would stop, wait for couple minutes, and start blowing hot air again, until temperature reaches ideal target.

I found that putting in new air-filter would help reducing the frequency of this shut-off. However, starting this year, it does not help much. I don't observe this issue during summer air-conditioning time. I read somewhere that this is considered as "overloading" which means somewhere in the motor is over consuming the electricity.

Thanks

The thermostat shutting off could be a limit trip.
But not much that you listed sounds like a blower issue.
You could test the capacitor.

Sounds like the fan and limit control is turning the furnace on/off before the thermostat is satisfied. Some older ones are manually adjustable but you need the device manual to know how to set the adjustments. What did you measure to determine it was the thermostat cycling the furnace and not something else?

As mentioned..... a thermostat that goes dead is most likely a high limit opening. That could be caused by a failing blower motor or as simple as a clogged air filter.

It's usually easier to use the model number for the furnace to locate a replacement motor.
