Is your furnace running but the air that’s blowing out of your vents seems cold? There are a couple things you can do to troubleshoot the problem before calling a heating repair company. You might have walked by a vent and noticed the air seemed cool. But is your home staying warm, at the temperature you set it at? If it is, the problem might be a simple thermostat setting. Check your thermostat and make sure that it is set to “auto” rather than “on.” When set to “on”, the fan on your furnace will blow continually, even when the furnace isn’t actually heating the air. So if you feel the air blowing out of the vents while the furnace is off, the air will seem cool since it’ll be at about room temperature. A dirty air filter restricts airflow into your furnace. Restricted airflow can overheat your furnace, causing a safety control to shut off the burners. This safety mechanism protects your furnace from overheating and the damage that causes.

So change the air filter if it’s dirty. Are you still feeling cold air come out of the vents after trying the above? Your best bet is to have a trusted heating repair company come diagnose the problem. But to give you an idea of what could be wrong, here are other common causes of this problem: If your furnace seems to be blowing cold air, it could be a problem with the ignition system. Basically, the furnace isn’t lighting the fuel, meaning it can’t heat your home, either.ac unit steaming Your gas supply could be turned off. outside ac unit making buzz noise but fan not runningOr the gas line isn’t supplying enough gas to your furnace. gold air handling athensThis can cause your furnace to lock down for safety.

Large holes and leaks in air ducts can make it seem like your furnace isn’t working. Cold air from your attic or crawlspace gets into your ducts through the holes. New, high-efficiency furnaces have condensate drain lines. Basically, this removes water that is created during the heating process. If the line gets clogged, it can activate a switch that prevents the burners from lighting.

Your refrigerator lights are on, you can hear the fan blowing air in the refrigerator, but the air is not cold. If this is your situation, then the repair is probably going to be a reasonably easy DIY job. When your refrigerator has working lights, the inner fan (or blower) inside the fridge is still blowing and the air is room temperature, then possibly the problem is the Compressor Start Relay.

The start relay is a small device mounted to the side of the compressor. It provides power to the winding for a split second at start up to help the compressor run. The other component that may have failed could be the Start Capacitor. The start capacitor acts almost like a battery to give the compressor a small boost during power up.The purpose of this guide is to give you some options to check yourself. The parts explained above may or may not be your issue but it is worth looking into before calling a repairman. If you are not comfortable with removing and replacing parts on your refrigerator, then call a repairman.The relay and the capacitor are what help start the compressor. The compressor is what produces the cold air to cool your refrigerator. If one of these two parts are faulty, then the compressor will not run and therefore there can be no cold air. The refrigerator can be on but if the compressor is not running the air will not be cold inside your refrigerator. This is a very common reason why most refrigerators stop cooling but keep blowing air.

If you hear a clicking sound coming from the back of the fridge, then the compressor start relay is most likely working properly and is not the issue. If this is the case then the next most likely part that has gone bad is the start capacitor. These 2 parts are cheap and can be found at appliance stores and home improvement stores, even local smaller hardware stores should have some basic parts. Refrigerator compressor parts can also be found online and at extremely reasonable prices. How to replace relay and or capacitor on a refrigeratorWe recommend unplugging the refrigerator from power and sliding it out from the wall. Remove the panel on the back bottom of the fridge and visually inspect the start relay and capacitor for signs of damage. You may find signs of melting or burned areas. These parts will be on the side of the compressor. Test the start capacitor first with a capacitance meter and the start relay. If one of these parts is burned, melted, etc, and you don’t have a meter, then you can either call a repairman, go buy a multimeter, order the part online, or remove the part and take the part with you to an appliance store and match it up with the same part.

How to install a universal relay on your refrigerator compressorThere can be other issues why your refrigerator is not blowing cold air such as a bad compressor, bad temperature control thermostat, dirty condenser coils, or even the main control board may be defective. (There is a refrigerator troubleshooting guide here that can help you even further if needed.) If the Condenser Fan Motor was defective, (the blower fan in the refrigerator) then you would NOT hear it running/blowing. This help guide is to help you troubleshoot when the fan in the refrigerator is still blowing but you do NOT have cold air.NOTE: Remember to always check to be sure that the temperature control dials or knobs inside your refrigerator are set correctly before you start removing panels and parts!If your air conditioner is leaking into your room, it may not be installed properly. When the temperatures start to rise, a window air conditioning unit can be a convenient, affordable way to beat the heat. From time to time, though, problems may arise with your unit that affect its performance.

Being able to troubleshoot your air conditioner can save you valuable time when you notice there's insufficient cooling. That way, you won't wind up frustrated -- and sweating -- in the middle of the next heat wave. Not Cooling Well If your air conditioner turns on but isn't cooling the room properly, check to see if the front of unit is blocked. Any item, including furniture, blinds or curtains, can restrict its airflow and reduce its cooling performance. If your unit isn't blocked and still isn't cooling effectively, however, check the condensing coils on the side of the unit. Cool air must pass through the coils before exiting the unit, so if they are dirty, it may be difficult for the air to emerge. Over time, the coils are likely to become clogged with dirt, dust and lint, but you can clean them by removing the unit's cover and using a soft brush or can of compressed air to gently remove the debris. If your air conditioner still isn't cooling effectively, its air damper may be open.

An open damper allows the air conditioner to draw in outside air, which can decrease its efficiency. Close the damper, and the unit's cooling performance should improve. No Air Blowing If you can hear your air conditioner running but it isn't blowing air into the room, there may be a problem with its fan motor. A window unit typically has two motors – the fan motor and the compressor motor. The compressor motor may be functioning, causing the unit to make running sounds, but the fan motor may be damaged. To check, turn the unit off and remove its cover. Try to rotate the fan blade by hand – if it's stiff and difficult to turn, you should have your fan motor replaced. If you find that the fan blade is easy to turn, the motor's circuit is likely experiencing an electrical problem. The issue may be with the unit's selector switch, capacitor or the motor, so you should contact a licensed electrician to handle the problem. Water Sounds Inside Unit From time to time, you may hear water sloshing around in your window air conditioner unit.

The sound may be alarming, but it's actually normal. Your window unit cools the room by drawing in warm, moist air and passing it through the indoor coil to cool it before blowing it back into the room. During the cooling process, moisture is removed from the air and usually collected in a pan at the bottom of the unit where it can be evaporated by the condensing coils. While the evaporation process is ongoing, it's common to hear water moving around inside the unit. You don't need to open the unit to try to remove the water – the only time to take action is if you notice water dripping out of the unit and into the room. Water Dripping Into the Room While your window air conditioner is designed to evaporate most of the water that it removes from the air inside your room, excess water does build up inside the unit. The unit should be sloped slightly out the window so any excess drips outside the home. If you notice water dripping into your room, check to see if the unit is angled downward toward the room.
