Bad valves from running with no refrigerant and no low pressure control.

The unit works on a curtain switch unless it has a KVS (varismart) transducer. Is there a dial near the red and green buttons?

If not then I would suggest recalling errors. Instructions for that...

I work on a ton of these indigo machines pressure controls are garbage. But never have I changed a control board I have noticed that when the pressure controls drop in and out it confuses the hell...

I just ran into this same problem on a new construction site. My problem is happening in all 4 rooftops. All VFD drives have phase loss errors stored in them. Unit work for a day and shut down. ...

It's pumped down. Did you install the solenoid, TXV or did they come installed already? Check the valve on the reciever.

I think the M3 is way easier than the M2 (not that the M2 was too complicated)

That works like a cap tube and has a constant flow of refrigerant and there should be a solenoid before it. Under normal operation that solenoid is open and refrigerant is flowing. So it would...

Not nessasarily if there is a solenoid in the little line then it would be normal when the unit is running to be dumping liquid into the compressor. Try cycling it off by either a ajusting the tstat...

Is this a scroll? Is there a liquid injector on it? If that's the case then if you close the receiver valve the liquid would not be injected but if you closed the accumulator than liquid will still...

You have it setup for a supply air bypass and you didn't tell the controller what it is. This is an advanced configuration and I recommend you call lennox and have them walk you through the setup

Couldn't see this leak I was trying fix today thought I'd use the camera as my eyes and decided to record it.

What did you clean the machine with?

Can't break red here either. In most cars the blower continues to run. Breaking at the transformer is ok ish. But most newer units have terminals on the board dedicated for smoke detectors

What's the head pressure? That machine at 90/70 makes ice in 18 min. Maybe insufficient compressor, txv? High head? Suction should be 25-27 at the end of the freeze. Head 240-250 5 min in. Yah you...

You're a better man than I. As soon as they pointed to the ABS machine I would have told them to call there coke distributor

With large emphasis on the low charge. Check the quick connects for leaks.

New prodigy startup checklist:

1. Make sure updated harvest assist motor installed.

2. Make sure to caulk wall where water leaks from evap section.

3. Order hinged curtain, relocate curtain...

Would it be to much trouble to put a hole in the curtain for adjusting the ice thickness control on your prodigy units?


I can deal with all the other design flaws. This one just drives me crazy...

Soaking them in a cleaner solution is probably a better idea then scraping them with a screw driver. For future reference

Clean it!

Then time it. If it's still to long check the evap for loose plates. If that checks out I like to hold a flashlight against the plate and look for cracks where the plates attach to the...

Depends on the brand. If it's a a York I probably worked right for a year. Now if it's a Lennox I love them.
