Once again. Best A/C channel on the platform on my opinion. Thanks for the master lesson

[alanmainwaring]

What you are describing is a stepper motor. This HVAC trade is becoming a very complex trade many thanks for doing this video.

[izzymoney]

I greatly appreciate you Craig I'm not really familiar with the EEV/LEV and you are just introducing me to it's purpose gracias sir for giving me a rundown on these devices and how they really work 👍👏

[YTsux-]

Great lesson as always Craig. We really appreciate the time and effort you take to make these presentations.

[ChiefBridgeFuser]

Crude but effective cut-away. Thanks!

[jamesortolano]

This lady’s nd gents is why you need to subscribe to Mr. Miggs channel.
Only testing resistance can you determine if the EEV, LEV is operational.
What a excellent explanation, demonstration nd visually satisfying post.
Thankyou so much Craig for all your posts, editing nd much needed content for us guys in the field ..

There are also different styles of stepper motors as and unipolar motors.

[zekenzy]

Great Video. Thank you for sharing. Have a nice weekend.

[Mareloko]

I’m going to start HVAC school this summer. Your channel has helped me so much already. I’m ready to feel proud about learning all of this. Thank you for teaching sir!
PS: any book for Rookies you could recommend me?

[SiElect]

Great Video Craig..Hoping I could have also the book for my reference.

[warenmann]

Informative video. On your site under quiz section the " Inverter Mini Split Quiz" question #10 asks " 10. How many thermistors are typically installed on a single zone system? above 0psi, the refrigerant...". what up with the " above 0psi, the refrigerant.." at the end... Thank You...

General question about EEV/LEV. Do six wire EEV/LEVs always have 2 commons and 5 wire ones just one common?

[otsqzwu]

Excuse me, I need a book on refrigeration, air conditioning and tender repair.

[rainbowgypsy]

How did you cut open so cleanly ? Ty for video !

[robertwynn]

Hi craig please can l ask if you could explain the air source heat pump install for a hot water system thanks from uk.

[Masterofrefrigerator.]

Can you tell me valve where the gets ground power for move the motor

[dennisivakhov]

Are they problematic?
They just look so tedious and junky looking

Compared to a piston that will never fail

Any feedback?

I usually install residential TXV equipment
never really messed with EEV yet

[Ray-wrwr]

What are the symptoms of the bad EEV ?

[imranshaik]

What are the symptoms of eev which remains open partially and liquid refrigerant flowing in stopped indoor unit in VRF system

[Adam-ulpx]

Is there any reasoning (besides price) for one over the other? The LEV looks like a Carrier product to me "look what we made, just like an eev, but more expensive and wont last as long".
