If your AC is malfunctioning, its probably due to a problem with the compressor. Dirt, dust and other materials built up along the condenser coil, preventing the air conditioner from discharging enough heat from the system. However, like any other appliance, these units sometimes develop issues. Refrigerant is moved through the AC system by a series of solenoid valves. This little component is used to give your system a kick start and should get things going again with no problems at all. The rooftop AC runs on 120 volts, not 12. Pump might be misleading, though, since the compressor moves the refrigerant by compressing it into a vapor (big surprise!). In some cases, a bad capacitor can potentially explode without damaging any other components in the RVs air conditioner system.

If fuses have blown or breakers are tripped, refer to a professional electrician who can help you figure out the problem. Its a good idea to get a new contactor if it has any problems because it will likely develop issues again sooner or later. Next, check the wall outlet with a voltage to tester to make sure it is working. This may have started after another problem in the AC unit caused the motor to work extra hard and draw increased amperage. The codes include: This code in PTAC units indicates that the air flowing out of the PTAC is scorching for regular operation and can only be fixed by cleaning the filter. Be sure to also look for any possible leaks and ensure the capillary tube is not restricted in any way. Second, if the motor problem was caused by overheating, dont forget to seek out the reason as to why! The unit should be unplugged, and capacitors (if present) discharged. This is a relatively cheap fix if you are near a well-stocked auto parts store. In older models, objects and bugs would stick in the contactor, and that would prevent the contacts from completing the circuit. If youre in a hurry to get your unit working again, trying replacing the start capacitor. A capacitor that has a bulged top is a clear sign that it is defective. These materials get caught up in coils and dirty grills, making the indoor unit heat up significantly faster. Like any other air conditioner, PTAC units will also encounter maintenance issues. The code also means that the wireless thermostat is no longer sending signals to the unit control. Defective Start Relays You might notice signs of burnout or the relay coming loose. Just like the capacitor, a starter relay, once defective, you will need to make a replacement. The compressor's job is to pressurize the refrigerant as it flows through the condenser coils, which are right next to it, and this is a process that generates a lot of heat. The amount of refrigerant in your lines is crucial for the compressor to work efficiently. Its fed by 120 volt, turning on the system will engage the relay and send 120 volt to the compressor. Prices of condensers typically range from $500 at their smallest to $2000. The compressor in a window-mounted air conditioner is at the back of the unit, which overhangs the outside of the building.
