Condenser fan rotating the wrong way

How do I change the direction of the condenser fan? The air coming out the top is cool instead of hot leading me to believe the direction the blade is turning is incorrect. The temp inside doesn't drop.

If nothing has been changed you have a bad capacitor and need to change it. Then the fan will run in the right direction. RUSS

Can I put a lower amp fan motor on a condenser if the one has a higher amps


Jason,

You air conditioning system is designed as an entire unit. All the parts were selected to work together.

The condenser fan motor has been selected to match system voltage, provide enough horsepower and RPM to spin the a fan with "x" number of fan blades with fan blade pitch or angle that will pull enough air across the condenser coil to cool the hot refrigerant gas enough so that by the time it reaches the expansion valve it will be in the ideal temperature range to provide maximum cooling in the evaporator coil.

Changing components with unlike replacements creates strain, inefficient cooling and potentially early failure of parts.

Tempstar Air Conditioner wont come on


Sounds like you need a new contactor in the condenser. The low voltage is grounded. Remove the low voltage (likely 2 wires) at the condenser and wire nut the wires leading inside. With an insulated screwdriver manually push in the contactor and be sure both compressor and fan run. Then replace fuse and turn power on to air handler with a call for cooling. Obviously the outdoor unit won't run because you unhooked the low voltage but if fuse doesn't trip then it's likely the contactor. Good Luck

Quasar cool look hq2061fh


Hello, some window units do not use a drain tube instead they use the condenser fan blade to scoop the condensate from the bottum of the base pan and splash the condenser coil to keep the condenser cool and also evaporate the condensate. Most of the time you can hear a "swishing sound"

The rubber on the fridge & freezer doors are hot


pull out the machine,remove the front bottom kick plate and then go to the back and remove the back bottom panel,check to see if the condenser fan blade is spinning and check the condenser coil to see if it's loaded with lint and dust.the fridge is running to hot,the way it cools down is the condenser fan blows air around to keep the machine cool and heat escapes through the condenser coil,if it's blocked with dust the heat is held in the coil,a shop vac works great for the coil,vac up as much dust as you can and then set the vac up on blow and blow the dust out of the coil,the coil will either be in the back or on the very bottom of the machine,if the fan isn't running try spinning the blade,it might run or something could be stuck in it,i've found from a piece of paper to a mouse stuck in the blade,if it is the blade you can leave the back panel off and stick a house fan back there to cool down the machine until you get a new motor,if the motor does run after you spin it i would still change it out as soon as possible,if it stops again you could damage the compressor and then it's new fridge time.you should clean the coil at least once a year.hope this helps and next time you need help send the brand name and the model number off of the machine that you need help with

Kenmore window unit 17,500 BTU turn on and blows great cold air for 5 min then just fan running after that with no cold air.


Sorry to hear of your problem.

This is a common issue, and have just experience the same in my home. I am also an HVACR service tech, and will outline the most common problem that causes this.

If it blows cold air, your compressor is working fine. For a certain reason your compressor is turning off.

The compressor needs constant cooling of the motor and its windings. The compressor is also equipped with an overload switch (this turns the compressor off when temperatures inside get too hot). This is probably what is happening in your case.

The condenser coil (the outside coil that is silver with all the vertical fins) is where heat is rejected. A fan blows air over the condenser to help remove this heat. The condenser needs to be clean at all times.

First thing - check the condenser for dirt/leaves/cottonwood. If it is dirty, use compressed air, or water to clean the coil, being very careful not to damage or bend the fins, this will impeded operation and cause you to lose cooling capacity. Clean in a vertical motion with the fins.

If you find the condenser coil is clean, check the condenser fan motor (the blades are usually made of plastic) for broken or damaged blades, and then look into the unit to see if the condenser fan motor runs if in fact the blade is intact.

I believe if you follow these steps you are either going to find a dirty condenser, or a bad motor/fan blade.

The only other reason could be a low refrigerant charge not allowing the unit to cool properly, but this can only be verified with refrigeration gauges and a trained service technician, unless you can visually verify oil spotting in the unit, indicating the presence of a leak.

Where is the drain hole on my haier air conditioner located


Hello, some window units do not have a drain hole for the condensate, instead the use the fan blade to sling the water on the condenser, since the condenser is warm/hot it will evaporate the condensate.

The cooling side is not cooling. But when I take it a part I can feel the cold air coming out of the condenser, and the evaporator fan is not running, therefore I am assuming the fan is not working. Is...


Greetings,
The evaporator fan comes on after holding in the door switch for about 20-30 seconds. If you do not keep holding in the door switch. It will not start. If this is a sxs refrigerator. the defrost heater usually goes bad..this causes ice to build up. The air can't flow thru the ice and the ff section gets warm. Of coarse, it could be any one of several defrost problems. The shaft needs to be held firm, while twisting the fan blade off in opposite direction while pulling up..this will remove fan blade. Please let me know if you do not see any ice build up

Does the product a/c have a drain hole?


Air conditioners of your type have tiny passages that allow the water (if clean) to go to the back of the unit where a splash ring on the fan blade whips the water onto the hot condenser coil, eliminating the condensate outdoors and subcooling the refigerant in the condenser in doing so.
If you have water inside and its level or slight tilt back , then you need to clean it up or forget it!

Condenser fan running backwards on heat pump


I am having the same problem, sometimes it runs in the wrong direction, blowing the air down. Sometimes something gets tripped and I need to turn the thermostat to off and wait a bit then restart it. If I am lucky it will run int the correct direction and also will warm the house. Sometimes it send nothing but cold air to the house's forced air.
