I've never seen or used one of those before. When I look on amazon.... I see different models. I'd say you bought the wrong item for your motor. You need one that matches your existing plug and socket.

You have an ECM X13 motor. You need this protector.

You purchased a protector for the ECM 2.3 and similar models. It is not the correct protector for your motor.

What IS the failure rate of these ECM motors? I see posts that the motors are extremely expensive and that they fail but the one in my Lennox furnace has been running for twelve years without any problem. I'll add that my return duct size is smaller than optimal and that I am pretty lazy about changing the return-air filter, sometimes finding it absolutely plugged with dirt and cat hair.

I first learned about these add-on surge suppressors when they could only be purchased from Zebra and for some reason (minimum purchase or high price) I decided to forego the "protection". They now seem to be an acceptable price and available from Amazon and other retailers. Still, after this long without a problem do I REALLY need one or would it REALLY prevent me from having to buy a new motor in the future? Or is it more a matter of the squeaky wheel getting the grease? Meaning, the ECM motor is a proven technology that has a low failure rate but the failures that DO occur get a lot of publicity?

I'll also add that I have a whole-house surge protector on my service (main) electrical panel. My standby generator is a Yamaha inverter and I have never had a problem when it is in use.

It is the luck of the draw. Some last a year or two and some a whole lot longer.

Not much of an answer, Pete. Is it ten percent of all ECM motors will fail? Twenty five percent? Or is it perhaps as low as two or three percent fail and even then fail for some specific reason such as overheating due to a plugged RA filter?

Probably more to it

Ecm motor failure is also more common in areas that have brownouts and power outages. River Oaks in Houston seems to have more problems than other areas around here. My company has always recommend a whole house protection device. It seems to work well.

If you want national stats you will have as much access to this information as any AC tech.
