Norlake sure can design some crap

It's illegal to not put an ECM back in. Sucks but just so you know. CYA

Please provide proof...?

I have had tons of failed EC motors on Russell evaps. I spoke to the factory and is seems they purchased a few containers of Chinese motors that had defective software. No service bulletin that I know of. They just send out replacements.

Lets see I was told the motors are fighting each other.

Keep us informed on the newer motors please.

Sounds like the motors are really fighting the moisture that gets trapped inside. What a $hit show.

I agree.

I'm very surprised as to why, what appears to be a common issue with ECMs used in refrigeration, can't be resolved simply by something like encapsulating or potting the printed circuit boards (PCBs) on these motors to protect the electronics from the inevitable moisture intrusion. Heck, it shouldn't be that expensive and certainly would cost a lot less than replacing in-warranty failures by the boatload.

These motors should be able to run totally submerged for several weeks or more in my opinion.

Here's an interesting article discussing such protections for electronics: https://www.electrolube.com/technica...h-do-i-choose/

The same thing happens in air conditioning applications. Even after they started encapsulating the circuit boards, motors fail for no good reason.

If they can't find a motor that'll stand up to basic walk-in cooler/freezer conditions, then they should stop selling these units until they do. If the price turns out a lot higher, that's the price of trying to be Green. Complain to your tree-hugging representatives in Congress about that.

There too busy dodging old girlfriends!

Its always amazed me how the open air motors last through the abuse in coolers and freezers

On the same token i never imagined a totally sealed ecm motor filling up with water...

Makes you wonder if an open frame ECM motor would hold up better.

And just where would their job security be if they actually solved a problem?
