Question about Heating & Cooling

Open Question

I have a GE 1/2hp motor (Lead-R-Line model 5KH47HR1086) used on an evaporative cooler that has sealed bearings and a mounting "disk?" on each end. Is there any way to remove the mounts and repack or replace the bearings?

SOURCE: evaporative cooler not getting water from water line

The pump is probably gone. the way it works is a float allows the water level to stay the same in the reservoir so check that. Water is pumped up to the hoghair and trickles down into it. A big old blower pulls the wet outside air into the room. We call that one a swamp cooler down here on the gulf. Go outside and spray some water on the unit to cool down the house till you can get the pump replaced.

The best way is to put a piece of metal down on the surface and seal it to the roof and then cut your whole for your ac. Russ

SOURCE: very loud - appears to howl - sounds like bearings

Careful: Some AC's are not designed to be oiled again once it leaves the manufacturer (while others do as) as to speaking of motors of ACs.

If your AC is making that kind of noise-racket, your AC is experiencing a loose part that needs to be re-tightened.

If it's specifically making a "rattling sound," like it says in this diagnostic article of a handyman site says, then it is likely that your AC fan is loose:

http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Central_Air_Conditioning_Making_Rattling_Sound.htm

In either instance, your best bet is to contact an experienced AC technician/contractor, as the making of noise is a sign of a serious problem that must be fixed right away, unless you would like to experience almost certain irreparable damage to your AC in my opinion--when sounds are made that's because two or more parts are coming into conflict with each other, causing friction, and thus damage, to occur.

Get free estimates from local AC/HVAC contractors in your area who would be in the position to fix it for you (or whom you can rely on to get as much infromation as possible during the free-estimate consultation so as to apply the information for your own use). The rule of thumb is to get at least three estimates. Good luck!

Could be the fan blade is the issue for vibration. Perhaps the blade was bent or somewhat damaged during failures or during the fan motor replacement process.

Might try replacing the blade. Be sure to install the correct blade. Pitch, number of blades as was on the original unit. If blade was replaced previously, the new blade may be pitched or sized incorrectly.

SOURCE: I have a bonaire evap

I am assuming you are talking about the fan motor. The motor should be ok, a torque "spasm" can be expected when it starts unless it has a drive to bring the motor up slowly. You didn't say that there is one, so I assume again that there isn't. Though it is variable speed; even if you start it on low the fan will have its largest load, you can check the alignment of the belt if there is one to the fan. If its a direct drive you can check the alignment of the shaft to the blade. I personally would pick up some brackets, or uni-strut and reinforce the mounting plate to put less strain on the motors standard brackets. I believe that would put my mind at ease. Hope this helps. Let me know if you need further assistance.Thanks.

How do i deal with the dripping of water from my Mitsubiishi split system from inside unit? Will putting the unit on 19 and then turning it full bore clear over condensing?


NO
the water is condensation from the humidity in the air turning to water on the cold evaporator core
normally it drips into a tray and drains away outside
if it is inside ( running down the walls it indicates
the drain hole and tube is blocked or the evaporator core is covered in gunk and holding the water up and not dripping where it is designed to
Call an accredited ac specialist shop to clean the fins and drain tube

Can't find a switch to change the direction of the fan. Not on the wall switch. Minka Aire F701-PW 52-Inch Pewter Delano Ceiling Fan


Generally, the fan directional switch is located on the lower portion of the fan's housing. It will be a 2 position slide switch. Up for Winter, Down for Summer. Do not try to change the direction wihile the fan is ON or rotating. In the Summer, the higher the speed the better. As it generates a wind chill, that fools your body into thinking it cooler that what it really is.

Hope this helped you.
