Charging And Troubleshooting Air Conditioning In Low Ambient Conditions 

Love AC in the winter time 😆

Watching from Papua New Guinea...

Never had to install one but now I'm fully infromed👊

Great content. Thank you for posting. 1. The temperature-pressure relationship on which the operation of this regulator is based is only valid for mixture of gas + liquid. The location of te probe should be close to the end of condenser where no hot gas/superheated vapour can exist. Putting the sensor on the liquid side of the condenser should not cause problems, maybe raise the pressure lightly. 2. The sensor should not be affected by (temperature of) the air. Blocking air flow around it with e.g. some sillicone sealant could be a good idea. 3. The fan should not spin below 70F measured by the sensor but it looks like it did spin. Have you checked that the fan stops at 70F by putting the sensor to 70F and below? 4. It would be a good idea to disconnect the fan manually and check pressures as a first step to confirm that the controller can actually do its job. 5. Obviously, the 'heat-pump jumper" was set correctly.

Well laid out video and explained in full detail👍👍. Good job!

We also rig units were I work with a cut in cut out pressure switch wired through a relay to achieve the similar outcome for low ambient conditions

I Installed this on a Trane 20 ton condenser and both of my motors over heated after 40 mins of run time. Spoke with tech support and confirmed that it was set up correctly. Was told that with that model unit I’d have to upgrade both the motors, add heat sinks, and rain guards.

For me just so I know it works and I don't want to be called back ICM makes a transducer that can be installed on the discharge .

Same issue I had today except on a rtu. Carrier.

Great tip💯💯💯💯

thanks for sharing

Great video! Thank you

I prefer pressure action on low ambient controls. I always add a freeze stat to the evaporator as well. I’ve also found TXV with a hard start kit for better in low ambient control. Depends on what the customer will pay for. Good video. Thanks and stay safe.

icm head pressure control does not come with the wire that connect the line 1 to the line 1 terminal. what kind of wire use to connect line 1 to the line 1 terminal?

never have good luck with those fan cycling, always find issues with them. I use the one that sense pressure not temperature

That's why we don't use fan control in refrigeration system it shows the different by using a fan control txv doesn't get liquid like a head master control.

Good video! Do you have any videos on wiring diagrams for walk-in coolers and/or freezers

Air conditioning in winter time call the ambient conditions go down to Goodwill or a thrift shop and pick up a six man or eight man tent cut the bottom out set up a tent it’ll be nice and 90° in there and you could set your sub cooling and superheat as if it was summertime in Florida Are use a pressure switch I don’t like the thermistor

Does this ambient control kit need other accessories Such as a hard start kit or anything else? And does it matter if its a txv or piston coil?

Hey man hope everything is ok I am always watching your videos,I worked on a carrier motormaster low ambient control today same scenario,it’s tricky to set the right evaporating temperature right due to condenser fan constantly speeding up and down some times you will run under 32° evaporating temperature for seconds and it will go back up,specially if there is low load inside the room,you can correct me if I am wrong I know you have much more experience then me too

fan cycle switch

Now whats that sleeve bearing and ball bearing ?

Can you go off of sub cooling at such a low temp?

What do you mean condenser froze up? Was it in heat mode?

York socks last time I called tech support it took 30 minutes

Those icm controls are junk, never last very long
