Reversing valve

[weezer81]

Pressures are equalized in cooling mode, seems to be stuck, liquid line sweating, greenhorn tech, goodman, it's clicking and calling for ac, rv coil didn't have much magnetic pull, changing it today, could it be the compressor, all help greatly appreciated

if the valve isnt switching why would you diagnose a compressor? do you get a bigger commission?

I can hear the valve switching, sounds weird not like a full switch, almost like it's bleeding, but the liquid line still sweating, compressor ohms good, clear to ground also, changing valve today, heelllpppp

How was the pressures in heat mode, equalized also, ( having your low side gauge hooked to the common suction? )

Is this for a customer? If so sounds like a expensive repair for whomever by not dialing in the root cause. Doesn't your company you work for have a senior Tech. versed in Heat Pumps?

I was thinking that also.
I have a policy in place where none of our average techs can diagnose an improperly shifting reversing valve without calling a senior techs.
It's just to much money to lose.

A halfway shifted valve is pretty easy to test for using a temp probe.
Goodman's service manual for your unit does a good job explaining this.

Thanx guys, it was the rv!

Light tap with a solid object should shift it completely & also your indoor fan will stay off if coil temp doesn’t get to the preset to switch it.

Nice lifehack. Thank you, fridg

To check if the solenoid reversing valve is functioning, it is necessary to measure the resistance of its winding with a multi-scale measuring device (amperevoltometer).
