Hayward SMX300055036 HeatPro Heat Pump Fan Motor, 1/3 HP, 825 RPM
Hayward's listed fan motor for HeatPro heat pumps.
The Hayward SMX300055036 is the 1/3 HP, 825 RPM fan motor that Hayward's service parts list calls for on all six HeatPro MCHX heat pumps, the HP21105T, HP21205T and HP21405T heat-only models and the HP31105T, HP31205T and HP31405T heat/chill models. Hayward's earlier heat pump manual lists the same motor across its 90,000 to 140,000 BTU sizes, and Hayward covers the part with a 1-year replacement part warranty.
Why PST Customers Pick This
Listed for Every MCHX Model
Hayward's HeatPro MCHX service parts list names SMX300055036 as the fan motor (item 6) for the HP21105T, HP21205T, HP21405T, HP31105T, HP31205T and HP31405T.
Earlier HeatPro Sizes Too
Hayward's heat pump manual 51300102101, linked from the HeatPro HP21404T page, lists this fan motor for every size it covers: 90,000, 110,000, 125,000 and 140,000 BTU heat-only, plus 120,000 and 140,000 BTU heat/cool.
Moves Air Across the Coil
Hayward describes the MCHX fan motor as an 825 RPM, single speed, 1/3 HP motor whose job is to move air across the air-side microchannel coil.
1/2 Inch Motor Shaft
The fan blade mounts on the 1/2 in motor shaft. On MCHX units Hayward pairs it with a 22 in 3-blade fan on the 110K models and a 22 in 4-blade fan on the 120K and 140K models.
2.4 A PSC Fan Motor
Hayward's specification tables list the fan motor at 2.4 A RLA, and Hayward's HeatPro pages list the fan motor type as PSC.
Starts Before the Compressor
In Hayward's MCHX operating sequence the fan powers on first, followed by a timed delay before the compressor turns on.
Service Notice
Hayward states its MCHX heat pumps are to be serviced only by EPA 608 licensees with HVAC/R training or technicians who have completed Hayward technical training, and that the units run on a 230/240 VAC supply. Hayward recommends turning the breaker off and discharging the fan and compressor capacitors before measuring capacitance, and grounding and bonding the unit per local codes or the National Electrical Code (NFPA 70).

Let customers speak for us
The product was delivered on time and came as advertised.
Quickly shipped and the best part is it now installed and working
You're the only one that had a 3.5" lens. I'm happy that it's one piece.
Good transaction, the only problem is I bought the wrong size allen wrench. I should have bought the 1/4” one.
All I can say is great customer service. Their products are good too
We had the older version and this dropped right in. Great buy!
I can’t wait for my mini Goldendoodle to be buzz for Halloween! It’s not bulky and small that it won’t bother him. He’s 32 lbs and I got the M/L
No issues with it. I received great customer service ensuring I chose the right thing and shipping was really fast.
Can not say enough about the Balboa retro fit system. I’m no expert, but I watched a you tube video and installed it myself. Hot tub is 14 years old and is up and running like new. Very pleased with my purchase. Thank you.
The process was smooth and lights arived as expected. Everything test out in good working order.
Needed to replace the control overlay on our Nordic Impulse hot tub, but could not find out the make or model number of the actual control panel on our tub. By taking measurements and photos or our actual control panel button positions and functions, I was able to narrow down the options. I ordered this overlay as the button positions seemed to be in the right positions, even though the overall size was smaller than the control panel. The overlay works, in that all buttons and functions are in the right place, and the overlay seems to have adhered well to the panel. It is not a perfect match, as it is smaller overall than it should be. But I am happy with the result and will buy an additional identical overlay as a backup in case this one, too, deteriorates at some point. Took a lot of detecting, but the result is successful!
This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.
