Question about Heating & Cooling

1 Answer

AC Unit is not cooling.

Unit is not cooling. It is taking in air in the return air, but not putting any out. Unit is also loose up top and making loud noises. rubber washers were worn out. I thought somthing was caught in the fan, but it was just a loose motor. I tightened the bolts up, but it still makes loud noises. What should i do about the unit not cooling, and what should i do about the rattle?

Hi...
Every air conditioner has a motor called a compressor. The compressor provides the cooling capacity for the air conditioner. If the compressor or its electrical controls are defective the compressor may try to start, fail, and create an electrical overload. If the unit does create an overload, every compressor circuit is also equipped with an overload safety switch. The safety switch is designed to protect the compressor from burning out. The safety switch will cut the power to the compressor for a certain length of time and then reset itself. When it resets it will allow the electricity to flow to the compressor once again. If the compressor then starts, the unit should function normally. If the compressor doesn't start when the overload resets, the overload will again cut the electricity to the compressor. This cycle will continue indefinitely. (Always allow three to five minutes before restarting the compressor.) If this situation is occurring, unplug the air conditioner and get help from a qualified repair technician. This problem is often fatal to the air conditioner because the cost of repair often exceeds the price of a new air conditioner...

hope this will give u a clear idea..
thank u
rate me!!!!

Turn on AC but outside unit fan doesn't move


Either a very bad Capacitor, or the fan belt came loose and the motor is just spinning

Unit makes a loud rattling noise when operating


Hello, most likely the fan blade is either loose or cracked at the hub causing the blade to hit the fan shroud. You will either have tighten the fan blade or have to get a replacement.

My Danby A/C unit makes these loud (almost) grinding noises when in Cooling mode and I try to lower the temp. Do I need to put water in the machine to allow the Cooling to start? I have both the vents...


No, the bucket is to catch condensate off the cooling coil, make sure the make sure the condensate pan is in correctly, it activates a switch for cooling. this sounds like a possible return to store

Carrier air conditioner isn't cooling the house. It is blowing air, but it doesn't seem to be cool air.


Check the outdoor unit to see if it is discharging hot air out of the top ofd the unit, check the insulated suction line to make sure it is cold or sweating. Try to listen to the outdoor fan and the compressor to make sure they are both operating

Loud rattleing sound


If this AC is a thru walled, since it is new it is better to inquire to the people where you buy this unit, for this type of problem. They must have some authorized repair man/shop or, use its product warranty.

The problem could be also uneven placement of its base. This could maybe hitting the fan guard, some loose connection or some foreign object left that's hitting something inside.

AC roof unit stops cooling after rain


No, the units are sealed and the rain should not have affected the system at all. I would remove the outer cover of the unit and access the capacitors. Your start capacitor may be bad. You can visually inspect this and tell if there is a problem. Small black relay on top of capacitor often burns out, if so, replace capacitor and relay. If this looks fine, then we need to start at the thermostat and work our way forward.

Thanks,

Jeff

Outside makes loud noise


I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter


Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.
