Squealing sounds from a forced-air heat pump generally occur when the belt that connects the motor to the fan slips. If the blower is making a grinding noise, shut off the unit and call a heat pump repair technician --the motor's bearings are probably shot. In most cases, the belt is improperly aligned or worn and needs replacement. Follow the instructions in your owner?s manual (if you don?t have one, contact the manufacturer and ask for one). This job involves removing the access panel, loosening a couple of bolts that hold the blower motor at the proper tension, and realigning or adjusting the belt. In many cases, it?s a good idea to remove it and buy a replacement at the hardware store. When reinstalling the belt, be careful not to over-tighten it--this can wear out the motor bearings.

There's no belt in these units. It's probably a warped blower wheel or bent blower housing.

    Thanks for the tip!!! Is it easily repairable or should I scrap the unit? Thanks for the info Tyler!!!

  • Tyler T Sep 02, 2012

    It's not that difficult on similar units but I've never done it on a Haier. It's definitely worth taking apart to see if it's something you're willing to tackle as long as you can get any parts you need. a Comment

Air conditioner fan is blowing but not air coming

If you mean that your OUTDOOR AIR CONDITIONER FAN MOTOR is blowing AND no air is coming out of the vents within your house, it clearly indicates to me that 1 of 2 things are wrong.

Either (1) your INDOOR AIR HANDLER is NOT running or (2) the INDOOR AIR HANDLER is running but your PLENUM has come apart.

If your INDOOR AIR HANDLER UNIT is NOT running, it could simply be the circuit breaker is OFF/TRIPPED and simply needs to be turned OFF; then turned ON. If that does not FIX your problem, then it is most likely your 5 micro-farad run capacitor for your indoor fan motor needs to be replaced. It will prevent your indoor fan motor from energizing. Worst case scenario would be your INDOOR FAN MOTOR has windings burnt and needs to be replaced. If your indoor air handling unit is equipped with a CONDENSATE VALVE CUT-OFF SWITCH, check to see if your drain pan is filled, thus energizing the switch. If the CONDENSATE VALVE CUT-OFF SWITCH is ENERGIZED, it will prevent the AIR HANDLER FROM energizing. That is the design and the reason for this valve.

Good luck.

What's wrong with your current AHU? Any Ruud dealer can assist you. Most 4 ton units work with r-22 or 410a. As a side note, most parts in an air handler can be replaced unless the case is rusted thru.

We have 2. LA125HV w/ 1 condensing 1. air handler

I could not find a "fault code" list for the LA125HV but for thier Multi Split Units LG lists code CH7 (C7) as "Indoor Unit is Set in Different Cool/Heat Operation Mode." So maybe your air-handler tihinks it's in Heat mode will the compressor is in Cool mode, or vice-versa....
