Lennox Variable Speed Blower Motor controller module easy repair

[@coolmandude1000]

Ted there is a motor company in Florida that have 1,000s of OEM ECM motors rebuilt for all HVAC brands that are priced at about $325.00 with a 1 year warranty. They also sell just the modules that are rebuilt as well with a 1 Year warranty for about $169.00. They ship out very fast as well. I have purchased several ECM Motors and just ECM modules as well and have had great success. I will updated this post a little later today when i get back into my office. Cheers man. Peace

Looks like United Hvac Motors is the company baeed on a google search

[@rj.parker]

Their refurbs include replacing "wear items" such as "bridge rectifiers and capacitors" along with a reflash of the program. The $169 price is for X13 modules, its $229 for ECM modules. They also sell motors with modules. I ordered an ECM module; the parts except for the transformer look new and the case was freshly painted. One year warranty. Pic of received unit bit.ly/ECMandX13 They said they have refurbed 167,000 units and currently have 26 employees.

[@joeshearer1247]

RJParker I don’t think they are selling them based on manufacturer model number they just go by the generic GE numbers and that doesn’t mean it will be the same motor at all as what failed. And are they unpotting all the silicone in the module to repair?

[@bcotterman499]

Yep, there located in Tampa, Fl. Have used them...good company, product and service. unitedhvacmotors.com/

[@nld-bl5ct]

My Lennox is still under warranty, it is just under 5 years old. The guy came out and spent a few minutes in our attic with me and said he would order a new motor. I don't think the motor is bad.

[@jefferygrady3181]

All these variable speed motors cost big bucks so to get you to pay a bit more money for a more energy efficient unit using them the manufacturer gives you a 10 year warranty on the motor! So after 10 years it will fail and now you are supposed to get a new unit because of the cost of replacing that motor on a now over 10 year old unit! Talk about planned obsolescence! Thanks for another awesome video TED!

[@Jon-hx7pe]

there's a universal replacement now for new units with ecm, it takes the firm-wear from the main board. the main benefit of variable speed is automatically getting the correct cfm across a large static pressure range and maintaining it as conditions change like filter getting dirty, balancing dampers being adjusted. for those who want lower repair costs, can get a unit with an x13 and retain the energy efficiency.

[@johnhaller5851]

It's somewhat better comfort, with the fan only running at high speed when really needed. Sell that to the customer, but let them know the ECM will go bad eventually. More service $ down the road.

[@Jon-hx7pe]

@@johnhaller5851 the customer doesn't have a choice for furnaces - all required to come with ecm motor. a question of whether to go for the cheaper constant torque or the more expensive constant airflow/variable speed version. In general high end equipment is much more for comfort than energy savings. I'm a fan of 2-stage/constant torque furnaces - so much better than single, yes, a bit more to fix but repair costs aren't as astronomical as the high end units with variable speed.

[@zulu123-x2d]

Do u need a particular thermostat for the variable speed to work, I have nest 3rd gen, and it sounds like it’s on or off, how to check, thanks

[@bill944]

The variable speed blowers in Lennox furnaces and alot, if not all, of air handlers comes factory set to slowly ramp up to 100% operation. Takes 7.5 minutes to reach full speed. This greatly increases dehumidification.

[@jameshengston6029]

Do you have power surges in your area? Have you checked your incoming voltage to ensure it’s correct and tried a quality surge protector on the unit?

[@mikegilpin8527]

Great video Ted. Its great to see that there are still some good seasoned techs out there that do troubleshoot those modules on those Lennox ECM Motors. That system doesnt look to be too old considering it being a three stage heat two stage cooling. Great Job!!!!

[@TedCookHVAC]

Thanks 👍

[@jayhatch7972]

Also Ted with the Lennox training I have had was informed all Lennox air handlers come set up as a straight cool only. You need to cut the blue jumper between the R terminal and the W2 terminal

[@gnme420]

I might be doing this same repair quite soon. My issue is that everything works but every day or two now, the thermostat will kick on and nothing will happen. The outside unit will come on, but the blower motor won't come on inside. If I take off the panel and decompress the door switch for a little bit, along with turning off the thermostat, everything will work again once reconnected. I have power going to the connectors for the ECM and the motor windings are within ohm spec from what I saw. I'm just getting tired of having to reset it every couple of days (or sooner). Hopefully this will be my fix as well! Any additional input is always greatly appreciated if there is something that I'm overlooking and might help me. Thank you for this informative video!

[@lovecaron1]

Is that black mold?

[@scotta9114]

We have a 2003 Heat Controller downflow furnace. We had it serviced and the Tech said we should replace it. I asked why and he said the new furnaces are 96+% efficient and have an ECM Blower. Our Furnace is 92% efficient and has never had a failure except for blower motor bearings failed. After seeing these videos we are not sure why we need to replace our reliable furnace?

[@Jon-hx7pe]

you don't as long as the heat exchanger is still good, u probably got a salesman.

[@scotta9114]

@@Jon-hx7pe It has dual stainless steel heat exchangers. We have carbon monoxide monitor's in house in case they fail and contaminate living area. Furnace still looks like new in and out.

[@Jon-hx7pe]

@@scotta9114 Many techs are likely commissioned. 10 to 15 years and it's out there door when there are 25 year old furnaces running safely and reliably. It's such a shame - a lot of good equipment gets scrapped and homeowners ripped off.

[@Kris-jk9mq]

I have had 3, yes three failures on my blower.. The coil windings inside the actual motor shorted out every time! (bent one straight and it burnt up somewhere else in a year) Replaced with a new motor and same issue happened.. On my 3rd motor with a spare ready now lol.. Wish I had that handy tester you made there for the ECM! That is cleaver!

[@nidalshehahadeh7485]

lennox cbx27uh blower motor works fine on cold setting yet it does not work with heat or manual fan , what is in control ? is it a separate controller or is the same as the module on the back of the blower motor ? controller on the back of the blower motor was replaced not long ago with a manufactured unit . thank you

[@buffordbaxter3370]

Good Job Ted! That unit is a 2008.

[@blackericdenice]

I heard variable speed motors don't last long. They did not say you could replace the module by it self. I love this guy. No homo.

[@saulortega8537]

High Static pressure in the hvac system is the #1 reason why the electronics fail Fix the ductwork and they last their normal life span, 12-15 yrs

[@jayhatch7972]

On that Lennox model it uses the y terminal calling to ramp the motor to higher speed. Just a heads up for you

[@nld-bl5ct]

I have a unit like this, and I cannot turn just the fan on as I could with my other AC unit. I switched out the thermostat and that would not fix it. Any thought?

[@ishalljr]

The cost of that motor is half the price of the air handler at the company I used to work for. Nice save!

[@jeremygoldsworthy]

I promise that was still not a cheap fix.

[@catsfightsandsights1957]

@@jeremygoldsworthy That module alone is almost $300 on amazon

Some companies are going away from psc motors altogether. Big tickets in the future. It's a dirty game

[@rogergregory6512]

Hey Ted, you couldn't have installed a evergreen motor?

[@saulortega8537]

Evergreen VS is the solution for constant airflow “true variable speed” Evergreen EM is the replacements for X13 ECM’s www.regalbeloit.com/brands/Genteq/Aftermarket-Products/Evergreen-Motors/Evergreen-VS-Motor

[@watermanone7567]

Ted: Was the fan motor turning the correct direction? Hard to tell in the video, but looked like it may be wrong way after the new module was installed. Thanks for great video's.

[@zone07]

Would a universal motor be cheaper?

[@Straight_White_Fatherly_Figure]

I never use those black lifting brackets. Nice work!

[@Garth2011]

Good repair ! Replace the part that is bad, not an entire assembly (motor and the electronics). It's amazing how the public is taken advantage of due to circuit boards and their cheap quality. It happens to cars and all kinds of things like microwave ovens, stoves, ovens, washing machines etc etc. CHEAP crap circuit boards while most of the mechanical stuff just continues to live and run and run.

[@sknight0391]

There appears to be some "slight discoloration" on the blower housing. 😲😳😉👌

[@Heavy_metal_rulez]

[@sknight0391]

[@The1JBanks]

probably improper installation and the water is blowing off the coil causing growth in the air handler.

[@JuanMartinez-df1lc]

Just from moisture

[@daviddesilva4971]

Good job, Ted. Well played. Thxs for the vids!

[@benderjrowe3599]

Even though it was a quick fix for the motor/module, I'd have pulled the cage out and cleaned it. And if that black residue is actually mold, I'd have taken the whole blower unit out and disinfected it before I put it back in. Also handy to wear your jumper wire like an HVAC Tech necklace.

[@joechambers09]

Does anyone know the model for lookup for that particular motor

[@joechambers09]

I ordered the exact motor and module used and when i hooked it up it only runs fast for 10 seconds and then runs medium speed which is not enough to push air..does anyone know why

[@pepsiman1957]

[@garyangelstad5212]

Hey Ted. Great videos. Lets me know what other equipment is out there and the problems and fixes. 99.9% of what i see is nat. gas. Have you ever attempted to repair the motor controller on a dc drive motor. I've seen other vids repairing thei rush capacitor on the 2.5 regal/beloit motors but mine has a burnt link on the backside of the motor controller board between the negative on the c10 and the red wire connected to the board. I was just going to solder a small piece of wire in there and test it but i thought i would see if you have ever attempted a repair like this

[@carlitosrosa7177]

Supco makes an ECM tester that does ECM 2.3 (16 pin), ECM 3 (4 pin), and X13, Evergreen, and other ECM motors for like $50.

Cost is $300 for module for these ECM disasters. You might save 300-500 over 15 years depends on kwh$, runtime, no one saves anything with these because they fail 3-10 years if lucky. Now since 2019 govt mandated these in all blowers, hopefully they fixed them to last like a PSC but I doubt it. In some cases with high SP they use same kwh anyway vs PSC which last 20-30 years.

[@scottk0623]

Looks a little moldy too

[@moodyga40]

that motor must have a switch mode power supply inside of it

[@MaMa-qh4dy]

Ecm are bad, bad, bad. At least this one was repaired with module only. Last year I had to replace my entire ECM condenser fan motor because The module was not separate from the motor. It was one-piece. That part cost me $900. Yikes!

[@joshadilman8397]

Great video great learn for me thanks

[@UltraHydrophobiccoat]

Those so called variable speed Lennox unit really save customers on energy? Maybe, but in the long run, it costs customers much more to repair the unit. A board costs over hundreds and up to thousands, some thermostats cost over $500. And HVAC technician spend more time on diagnosis. Keep it simple in HVAC field, manufactures!
