I think it's just the opposite, the on and off will do the damage to the motor. The on and off will pull high current and damage the motor modulation of the head pressure control will keep the current down. I think this type of pressure control is just another way of VFD. This is the control I use and have been using them sense they came out well over 20 years ago. Good call for using them.
The "A" team is together again!!!!!
Another awesome video.. Thanks again for all you do.
Great explanation after you finished. Good job Mike, you are obviously learning with the best. 👍🏻👍🏻
Thanks 👍
Nice video
Always loved the wiring vids ... I was thinking Wago lever-nuts at the same time you mentioned lever-nuts doing all those different sized wires ... Lol ... Good vid ...
Buen trabajo.
The wolf in full effect.
Only heat pumps need crankcase heaters. I guess they can't open the windows in an office, so you have to run the a/c in cooler weather.
exactly, some places have to run a/c year round, so you add crankcase heater, fan cycling/pressure controls and other junk to make it keep working and not self destruct
Would you use a winter start kit with a fan cycling switch instead?
Recall that the tech on Comfortplus Heating and Cooling used a heating pad on one until he could get a kit. Worked.
So, how do you like the transit van?
The kits are compatible with PSC and direct drive motors. This covers most residential systems. The controller will start the motor at max voltage for bearing lubrication, then ramp down to setpoint. They get a bad rap because of the low sleeve bearing temp when running at a lower speed in cooler weather which may cause motor seize up to over time. I’ve only seen one failure from seizing, among many in operation in Tele Data rooms without issue.
Is the motor master a self-contained variable frequency drive? I don't understand how it could vary the speed of a PSC motor otherwise.
@@jeremymcguire7069 Good question. The device varies the impedance on the single speed/single phase winding which inversely increases/decreases induction motor voltage. The VFD uses an inverter DC-AC, and pulse width modulation for speed control.
@@jammin345 Thank you for explaining how it works. I looked at Carrier's website and the installation document, but it wasn't helpful for explaining the actual design principal.
@@jeremymcguire7069 It's basically a dimmer.
Great job is this kit works for all kind of condenser units or only for carrier
Any condensing unit
Ok
Just curious why you don't use the Malco bit with the ¼" and 5/16"
Heads to big
@@WillieMakeit they have a bit with different head that's slimmer bit get what your saying
24ecb36. 2 or 3 ton?
3 ton 13 seer
Hi there MI Heating Guy. Not too long ago I had asked you about replacing a TXV on a 2009 2.5 ton Carrier infinity series air conditioner/heat pump. It was replaced but apparently the unit also had a failing dual capacitor; it was leaking oil. It was replaced as well. Condensing coil was cleaned as part of the spring maintenance. There was one important question that I had forgotten to tell the tech that maybe you could answer. Towered the end of last summer when the condenser unit would first turn on the compressor would briefly get very loud, then go back to normal decibel levels. It would pulse up and down like that a few times until maybe 5 minutes into the cooling cycle. Then that noise would stop and the compressor would sound normal. It would not do this every time it started up. Your thoughts? It has a two stage compressor.
What model condenser
@@MiHeatingGuy Seral number: 1709E07741
Not sure on that 1
I put a 521 hard start kit on mine.
S/N 1709E07741, may not be correct to what you have, it shows as 15 SEER 2-ton single stage Performance Heat Pump, 25HPA524A...
Looks identical to the ICM head psi control
Carrier just put their name on it?
That's all it is is ICM control
@@MiHeatingGuy .... gotcha... figured it was... I use em sometimes on refrigeration equipment... keeps good column of liquid feeding txv’s
Never had good luck with those controls. Prefer a pressure control.
Wagos
As Dan indicated, those "lever nuts" are called Wagos. Once you use them, you will never go back to wire nuts again. Try them out.
Those things are high as giraffe p...y my boss won't pay for those.
Stomach of steel. Taco Bell?
Nerves of steel. Sounds like a natural disaster or mass murder going on in the background.
