Carrier RTU

[John Culpepper]

Carrier RTU M#5OTJ-O16---51OYA S#1796FO3228. Do I have to pull of the top of the unit to get the blower motor out? It looks like that will be the only way, the wiring is too short to reach out of the filter door to unwire motor.

Thanks

The last one I did, that's how I handled it.

Use heavy cardboard or some plywood to protect the evaporator, in case you lose your grip. That way, you don't spend half an hour trying to straighten fins.

The next one I write up, I may try to create some sort of support to sit the motor on, since I do these alone, with no helper.

Yes you do. I've done them before and it's not to bad. just pull the lid and set over the condenser section, this will open it right up.

Thanks for the quick reply. I kind of figured that is what it would take. It was a wierd situation where the motor was ok but it had broken the plug welds between the motor and the base.

Again thanks!:D

I see that fault on newer Carrier unit motors, too.

I almost want to buy a little mig core flux welder for the truck. Almost.

Top panel must come off to get back there... PITA... I had to do one last summer, not as bad as I thought, but still a PITA!

Only when I have something that is too heavy for one man to rope up onto the roof himself. :(

Harbor freight has an inverter DC stick welder about the size of a lunch box and maybe 16# does a great job I use mine to weld condensers to stands on roof and broken fan mounts on roof top condensers have also welded broken walk in door hinges on sale $100.

The thing that bothered me was how small the motor base was compared to the motor. If someone was to overtighten the belt the welds on the base are doomed. And to top it off, the motor is a special order part made special for Carrier by G.E.

[plee]

Speaking of the base being weak, I had to replace the all thread rod that runs through the base to tighten the mounting plate down. The previous tech didn't catch this and went through a couple of belts since the motor was satting slightly crooked to the blower pulley. If Carrier is going to use such a large motor which is probably necesary they should beef up the mounting.

Carrier is like Chevrolet, it used to be good now it is junk.
