Our unit is making loud clicking noise and spraying water when in the cooling air condition mode, but not when the fan is on. What could be the problem, and is it fixable?

water pump, replace it and pads

The main fan that cools the lamp is mostly high speed when the unit is running. when it shuts down it slows the fan down, until it stops in standby. So the noise is only really loud when it is showing a picture.

try setting the fan to eco mode (slower running) and see if the noise is acceptable. If it is still too loud then you will have to replace it. Have a look at the fan and see if any of the plastic blades are missing.

1. Could be a caught foreign object between A/C (air conditioning) fan and cooling radiator, producing this loud noise.
2. Could be a damaged fan blade, mowing the cooling radiator.
3. Could be a loud noise comming from the fan's electrical motor.
4. Could be a broken off fin (small wing) of the cooling radiator, striking the A/C fan, producing this loud noise.

I install them every day and I have not had one make a loud grumbling sound. Sounds like you might have a low voltage (Thermostat) wiring problem. The only thing different inside the indoors unit from heat and cool is the fan speed, electric heat when on. The fan might be loose or out of balance and it only shows up at low speeds. Either way, the noise is not normal.

If it is rattling when in either fan or cool, you are having either a fan motor problem or the blade is hitting something. The water may be from a clogged drain port (by coil) which u are not seeing, if a new one is under 250, that is your best bet!

You could have a stoppped up drain passage from the evap coil to the outside of the unit. OR it could be leaning too far inward not allowing the condesate to drain out. Check to make sure the unit is level, and if it is, then pull it out and clean it out. you can use a water hose, but be careful not to get the electronics wet. The passage is usually plastic or styrafoam an at the backside of the evap(inside)coil.

If it does not make the noise when the fan is ruunin you may ahve abroken sping in the compressor. Make sure you Window unit is level. If not the compressor will knock on the inside. Rusty

I sell Rudd equipment. You have air in the system or faulty TXV. Replace TXV and evauate system. No more problem. Rusty

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.

Is this a wndow unit or central air system? if this is a window unit , your problem is it only needs cleanning (dirt dbber nest-- trash around the back blades-- or the unt is twisted and rubbing the fan shroud. Last but not least, the slinger ring around the back blades (a ring around the end of the blades thats picks up water in the bottom of the unit and sling it on the coils to help cool the hot gases....Thank-you Thank you Thank you very much!
