Rheem Central AC Model RAHE-036JAS FAN STOPPED, unit seems working
Posted 13 August 2011 - 08:12 PM
but can't email users in there, maybe cuz i'm new user. so turned on at thermostat as usual, a few minutes i hear a loud buzzing so looked and no fan spinning. don't know if it was spinning for first few minutes or not. fan moves freely both directions. waited ten minutes and hour to restart, no spin.
could it be fuses only and not motor? is there online manual so i can see how to change fuses first before trying other stuff unless it can't be fuses only. turning on at thermostat seems like rest of unit is working as usual just no fan. have not had any work on it or motor replaced since i moved in 6 years ago. it's a 1992 model
rheem classic x super high efficiency, Model RAHE-036JAS made 6/92, serial 4013 F2492 4047, 208/230 1 phase 60 hertz compressor 15.5/15.5 LRA 81 Outdoor fan motor FLA 1.3
min supply circuit 21/21 max fuse or HACR 35/35 amp min fuse or HACR 25/25
i'm handy and do basic electric and construction and fixed my heater so hope i can fix this but first time on central air, thnx guys, much appreciate it,
sweating it out!

Next thing to check , is the contactor pulled in? is the unit getting 24 volts ac on the thermostat wires entering the unit?
if both of the above are ok , take a peek at the capacitor( the silver round thing) . It should be totally flat on the top. if it is not , it is failed. and a failed capacitor will keep the unit from starting.

yep all that is good, cap is flat, have current, contactor pulls in, no leaks anywhere, except old oil leaks under motor bottom and i never put oil in that thing for 6 years. and it's a 92 emerson long pole . is ur guess it's the motor? it's my guess but i'm not hvac guy but that's my gut feeling. know a place i can a good oem one and not a cheap one that'll only last two years? i don't think i can buy from johnstone supply since i'm not a contractor
it's on ebay too by same seller
but would rather get local in Los Angeles or at least online where i can return/exchange, and i've watched vids on youtube for replacing the motor and that will be a snap. question though, is there some balancing or correct height the fan needs to be set at? if so how do i do that, i didn't see the guy do that on the hvac youtube video

Have you tested voltage or anything else I asked for? YOU CANNOT just guess that it might be the fan motor just because you do not see it spinning.
When you turn on the unit does a Crapload of heat come out of it for a while?? if the answer is no , then the compressor is NOTrunning and you have a no power or failed capacitor problem.
GO buy a meter and check back when you can give some definite answers. No Guessing !

(as noted capacitor has no leaks and is nice and flat all round) sorry for the newbie eagerness;)

Buy both to be shure. you should replace the capacitor any time you change a motor.
If you are not going to get the OEM motor(that would be best), The best "replacement" motor for a rheem unit like yours would be an Emerson "rescue" motor .they have the side taped holes to mount to the top of the unit. Plus they are ball bearing motors.
You are on your own if you want to find one locally. There is bound to be a shop that will sell to homeowners.

After you take the top of the unit off . take a photo. that is the easiest way to figure out where to put the blade. You basiclly want the blade as close to the motor as possible without it hitting the motor. sometimes that means cutting off mounting studs. Be very carefull when removing and reinstalling the blade. if you bend the thin aluminum blade you will unbalance it and the whole unit will shake.
