Hello, I need assistance in discharging the capacitors on my GWHD room air conditioner. I need to clean the coils and fix a few bent fins on the condensor before summer starts, but I was told I need to discharge the capacitors before preforming any work on the unit. How do you discharge a capacitor? What does it require. Some help would be greatly appreciated!

Re: Gold Star GWHD5000 capacitors.
If all your doing is washing it out and fixing bent fins it's not necessary to discharge the capacitors. I would only discharge them if I was disassembling it to the point that the capacitors were out in the open or there was a change I could touch the wires on them. To discharge any capacitor is pretty simple really, first make sure the airconditioner is UNPLUGGED , then using two screwdrivers, make sure that you are holding onto the INSULATED HANDLES ONLY, put the tips of the screwdrivers on the terminal connectors on the capacitor and cross the screwdrivers. Sometimes, depending on the capacitor, it is possible to do this with only one screwdriver by shorting across the terminals with the shank of the screwdriver. Just make sure the A/C is UNPLUGGED and you are holding onto the handle ONLY.

with capacitors it doesn't matter which wire goes on which terminal
if it has just 2 terminals then a wire on each
if it has 4 terminals then one wire on one set and the other wire on the other set
A set is two terminals side by side
However if you are still undecided , get an electrician to fit the wires.
It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in. You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.
If the compressor is running but not cooling then I would start by cleaning the filter and coils as good as possible.If you can safely cut power and wash the coils then that's what I would do. If not you can blow it out with air and use a fin comb to straighten any bent fins to maximize air flow. Check refrigerant pressure and add if needed.If the compressor is not running you can replace the start capacitor and if that doesn't fix it then I would strongly consider replacing the unit. I have very seldom found it cost effective to replace compressors because by the time you are done you often have the price of a new one in repair costs.Hope this is of help to you. Good luck and thank you.
Download this illustration and then using a good multimeter start basic troubleshooting.
residential window air conditioners have a cooling system made up of
four primary components, a compressor, an evaporator fan, a control or switch, capacitor.When the thermostat is calling for a colder room temperature the compressor is energized. It is
normally very quiet.
evaporator is always located on the front of the air conditioner. It
also has silver fins. Be sure it is clean. Use a foaming type cleaner and rinse with plain water. Because the evaporator is absorbing heat, it is very
cold to the touch. The temperature drop causes any humidity in the air
to collect on the evaporator - sometimes called sweat. There is a fan
inside the air conditioner that circulates the air for the evaporator
and condenser coils.
The circulating fan and compressor are running
simultaneously. The fan motor has two fan blades attached to it on
either end. The fan blade on the inside part of the unit continually
draws room air over the evaporator coils, which are cold. The fan blade
on the outside part of the unit continually draws fresh outside air over
the condenser coils, which are warm. Because the evaporator coils are
cold, they cause moisture in the room to collect on them, much like a
cup of ice water on a warm, humid day. When the amount of moisture
increases, it begins to drip down off of the coils into the bottom pan
of the air conditioner. If the compressor fails to start or the fan you may need to replace the capacitor. You may need a hard start kit.
Thermostat control The
thermostat on a window air conditioner works by sensing the air
temperature entering the air conditioner. As the air entering the unit
reaches the set temperature it will cause the compressor to turn off.
The blower may continue to run depending on the selection chosen on the
control panel. Digital thermostats work on a similar principle but
display a more precise temperature. Test for continuity with the multimeter between the two terminals . Warm you should read continuity (contacts closed). If not change it. Selector switches The
air conditioner selector switches allow the user to choose the fan
speed. The compressor always runs at the same speed regardless of the
settings. If low cool is chosen, for example, the fan runs at a slower
speed but the compressor still offers the same cooling capacity. There
are other switches to control louver operation and other features on
Hello, ice will form for one of two raesons, either low airflow or a low refrigerant charge. Start by checking the filter to make sure it is clean, then check the blower wheel and make sure it is clean. If the unit is clean then the unitnis low on refrigerant and will require a hvac tech to come out and recharge the unit.
Hello, there are a few thing that can cause a Air conditioner to not cool well enough. First off the airflow should be checked, filters, evap coil to see if they are clean. Secondly the unit may have a leak which is causing your unit to loose refrigerant and therefore not cool well. Have these two areas checked out on your air conditioner.
E4 is an"Abnormality of Outdoor Unit." There are many reasons. 1. High discharge temp due to condenser coil blocked or less rpm of fan motor. Clean coil or replace fan capacitor.2. No gas and hence pumping oil. Find leak and arrest it. Recharge gas.
Its one of a few things, your fan motor, or fan capacitor, or also possible fan control. but popping could even be the fan disconnected from the motor, can you unplug it and safely take it apart remembering were each piece came from screw etc, an let me know what you see inside (do not touch or test the capacitor with discharging it first).
