One reason for using a PSC motor is that it lasts longer and costs less to replace. PSC motor is about $200 plus capacitor and relay and install less than $500. The ECM motor can be $1000.00. Simple items usually run longer with less problems.

Can you use a contactor instead of a relay?
@johnjennings-JJ
@johnjennings-JJ 8 ай бұрын
It may be a little over-kill but sure! Switch is a switch (as long as it can handle the amps of course). May have a little noise with it but should function the same as a relay. Just be mindful of exactly how you wire it up if you use both sides of the contactor and if there are extra speed wires don't put them together or on the same connection as the speed you are using!

The X13 ECM motor's sole purpose is to allow the HVAC manufacturers meet the increasing SEER rating requirements. The cons of them outweigh the pros of them. They are double and sometime tripple the cost of the PSC motors with a third to a half of the life expectancy of PSC motors, often have very short warranties sometimes as little as 1 year depending on the manufacturer while all the other components in the equipment have 3-5 years. They are very susceptible to moisture, so in climates with high humidity the failure rate is high, Almost all of them are made with substandard quality components made overseas that have low QC standards. As far as the new high SEER ratings, unless the home is very well insulated with R-38 or higher, has duct leakage of under 5%, and has doors and windows of ER 34 or higher, the significantly higher expense of the 15 and 16 SEER units will never be recouped in the energy savings.

Went to a call and ecm/x13 style motor is bad. No warranty left and it pretty expensive to replace. Unit currently has 3 low voltage speed taps being used cool, heat, fan, which connect to IFC board. Can you still convert to psc?
@johnjennings-JJ
@johnjennings-JJ 2 жыл бұрын
You can but just keep in mind that you lose the efficiency/design that the manufacturer had for the unit.The idea is that it would go back to being a standard wired thermostat and relay to control a single speed PSC motor. (or a single speed at a time on a PSC motor)

I was eating popsicles on the front porch! I don't remember if I said it in the video or not but my coworker had to replace his X13 2 or 3 times in both of his air handlers. He wasn't happy to rewire it for a PSC but he was tired of the cost and aggravation. Now he just has a 'G' circuit controlling that 90340 relay coil. Same speed no matter the call on the thermostat. Works just fine!

@@johnjennings-JJ Have another question?Had an RTU unit yesterday that had a failed ecm/x13 motor. High voltage to motor 208 Checked low Voltage to motor and only had 22. Transformer set at 230. Switched to 208 checked low V and had 25 now but motor still wouldn’t engage. My question is could the incorrect low voltage caused that motor to fail? I ohm’d the windings out and had 3.4 on 2 out of the 3 legs but one 1.8 on the one leg. Unit installed 2016/2017 and has been running like that 5-6 years.

Yes. I modeled this wiring after an air handler with a fan board that only uses one speed for both heating and cooling. It is typical in a goodman unit with a psc motor.

@johnjennings-JJ
@johnjennings-JJ Жыл бұрын
It doesn't matter if it is a PSC motor with only one speed used. If you had a a relay that did separated NO and NC switches then you could power 2 speeds depending on electric heat or heat pump. Then it could be determined by whether or not the "G" circuit was energized.
@biblebloopers946
@biblebloopers946 3 жыл бұрын
To hook up low speed you just connect your low speed to number four on your relay and number five to the load side of the heating contractor. Then you would have low speed during Heating and high speed during cooling but unfortunately you would also have high speed during heating if someone switched it to fan on during heating mode

We could probably make it work by adding another 90340 relay...just to completely separate the heating and cooling calls but then again...that is why we have circuit boards! Like i said in the video, i would not do this but it is fun to think about how. Thanks for watching and commenting.

A x13 motor, is a unreliable motor ,ask any contractor out there,I would be all in if they had the reliability, a psc will last 10 years and over, u do good if u get 5years out of a x13.x13 imo a piece of junk, forget the correct info on ductwork incorrect,(which is correct) but the psc will take more abuse from the idiots that will not design the correct ductwork.ive did this many times with a relay .simple and will last .end of story.
