Control panel problem

I have having a problem that seems to involve the starter system and control panel on the condenser unit. Could this be caused by dust and moisture on the control panel as it looks like it is not very protected from the elements?

    What kind of problem are you having?

  • dubbartlett May 14, 2010

    the condenser would not start until after power was removed from the control circut for a while (to remove memory?) The compressor runs now but sometimes when it shuts down it seems to monemtairly step down to a lower labored speed.

The unit not starting until you removed power from the control board suggests you had some kind of fault. Where there any blinking lights on the control board before you turned it off. These would give you an error code and help in diagnosing the problem. I'm not sure about it sounding labored before it stops. You could check on that by connecting a clamp on ammeter to 1 of the compressor wires and checking the current draw when it stops normally and stops sounding labored.

What causes both cooling fans to not run?


Hi Naomi , there is a lot involved in the control of the cooling fans on your vehicle ! There are three fuse's , three relays an a fan control unit !
1. radiator fan main relay , located in underhood relay box A
2.condenser fan relay , located in underhood relay box A
3.radiator fan relay , located in underhood relay box C
4.Cooling fan fuse # 47 20amp. underhood fuse / relay box
5.condenser fan fuse # 50 20amp in underhood fuse / relay box.
Any one of these could cause them to not work, rather then just replacing parts an wasting money you should take it to the repair shop !

The refrigerator not as cold as before


Things to check - door gasket seals for leaks, dirty condensers that need to be cleaned and dust removed, proper clearance to the back and sides of your unit.

Is your evaporator fan in the freezer functioning normally ? is your freezer cooling normally ? You might want to check at the back of your freezer panel for overfrost on the evaporator that will impact cooling performance. You can shut down your unit and try manually defrosting and melting the ice and then run your unit for a couple of hours to see if cooling is back to normal........ if it is, then your defrost system is malfunctioning and you will need to have the control board and/or defrost system components checked.

Otherwise, if overfrost and door seals and dirty condensers are not an issue and you have also tried raising the cooling dial up and compressor run-time is excessive then you may have a sealed system issue but rare and not the common causes. Most common causes are overfrost on the evap / defrost timer problems and damper (flaps that do not open properly).

you will need to have those checked if all else fails.

Vacuum condenser light of sub zero 650 is on - how to clean it


We recommend vacuuming your condenser every 3 - 6 months. Cleaning the condenser is important for the overall operations of the unit including cooling functions. A dirty condenser may lead to warm temperatures in the refrigerator and freezer. It may also cause the unit to run excessively. It may contribute to condensation or frost inside of the compartments. If the condenser is not cleaned properly it may even cause premature failure of mechanical components in the unit. Condenser Cleaning - All Models Before cleaning the unit, shut the electricity off at the control panel. When you clean the condenser, wear gloves to avoid injury from the sharp condenser fins. Use a soft bristle brush and vacuum to remove dust and lint from the condenser. To avoid bending the condenser fins, be sure to vacuum in the direction of the fins, up and down. Clean the condenser every three to six months or sooner if you have pets. 600 Series Framed and Stainless Steel louvered grilles: First remove the grille screws located at the bottom of the grille. Tilt the top of the grille forward and release the springs from behind the grille, then lift off. Overlay Panel Grille: To remove, lift up then pull out at the bottom and down to release from its mounting bracket. Remove the two black screws in the lowest louver of the grille. Tilt the bottom of the grille out and away. It will release from the top of the grille. Model 601RG Stainless Steel Grille: Remove in a similar fashion as the overlay grille panel. 700 Series All Units: At the bottom of the unit, remove the four screws holding the kick plate/grille in place. It will then slide forward, giving you access to the condenser area. 400 Series 424/424FS At the bottom of the unit, remove the screws holding the kick plate. The condenser is located behind. 427/427R: Remove the four screws holding the kick plate/grille in place. It will then slide forward, giving you access to the condenser area. 430: First remove the screws located at the bottom of the grille. NOTE: These screws (Phillips head) are accessed with the door open. Tilt the top of the grille forward and release the springs from behind the grille, then lift off. 200 Series 245, 249, 315W Remove the kick plate at the bottom of the unit, giving you access to the condenser area.

Lg bottom freezer is always unpredictable!!?!? many times its on a defrost cycle that we cannot figure out WHY??!!! we are upset opening the freezer to again see all of our frozen foods not so frozen!...


The LG fridges are all controlled by the board. Depending on the year of your unit, the unit will go into defrost once every 12 hours on the older boards, and once every 24 hours on the new ones. The older boards, were 12 hours, these were also the ones that had the problem. On the back of your unit, open the panel that covers the board, if it is 6871JB1375A it is old and could be the cause for the problem. You will need the xxxx1375D this is the modified board that should solve the issues.

Unit no longer heats


Hi,

If ur AC is not coolling properly thn u must go for replacing a fuse, resetting a circuit breaker or checking to see if the thermostat is set properly. If an electrical problem isn't the cause, the refrigerant may be low if the system still runs but does not cool properly. This can be corrected by having an EPA certified technician add necessary refrigerant. Most likely, if the problem involves any major part, such as the compressor, you would hear strange noises similar to those of any mechanical equipment not running correctly, or the unit might not run at all.


Go for replacing both theoutdoor condensing unit (which includes the compressor) and the indoor coil on my central air conditioning system at the same time
Matching a new condensing unit with a new coil is the only reliable way to be certain you are going to get the rated efficiency of the new equipment. Matching a new, high SEER (seasonal energy efficiency ratio) condensing unit with an old indoor coil probably would not result in optimum efficiency.

Goodluck,
Dont forget to rate me as fixya..
