SOURCE: American comfort portable heating & a/c unit.

Three things come to mind. First, if its on an extension cord make sure it is rated for appliance use. Undersized cords will cause the compressor to trip off. Secondly, I know it sounds stupid, is the thermostat set below room temperature?, And third, is it possible that the cool air, that it is initally blowing out, short circuiting and being pulled right back into the filter section. Like if a curtain is hanging over it or its behind a door? Good luck

sounds like you need to wash your condenser coil. Sounds like your compressor is kicking out on high head pressure. Once it cools off it starts cooling again take it out and give it a bath don't get the electric wet.

Precor error 20


Precor Error Code 20 Error Code: 20 Manufacturer: Precor
Model: All Models
Error Description: Error 20, Too many Maximum Power Requests in 1 Second - The error 20 observes a treadmill's power bit reading when the treadmill was operating at speeds of 1 mph or less. Power bits indicate the relative time that the motor controller drive circuit is turned on. Power bits is an indication of the amount of power the load is demanding from the motor controller. Error 20 indicates that at a speed of 1 mile per hour or less, an excessive amount of power is being demanded from the motor controller for an excessive length of time. Possible Reason:
  1. Starting the running belt under a very heavy load can cause the error 20 to appear.
    1. The user (especially a heavier user) is standing on the running belt as they start the belt into motion.
  2. A badly worn deck and/or running belt can cause the error to appear when the user steps onto the belt.
  3. Badly worn drive motor brushes may not be making proper contact with the drive motor commutator causing the error to occur when the user steps onto the running belt. The unit may also slow down or become sluggish when the user steps onto the running belt.
  4. A leaky or shorted drive motor filter capacitor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
  5. A leaky or shorted drive motor inductor (on units equipped with SCR motor controller) could increase the current demand enough to cause the error.
  6. The high power demand is caused by a shorted or de-magnetized drive motor.
Recommended Action:
  1. Instruct the user to straddle the running belt while starting the treadmill at a low speed, such as 1mph or less, and then step onto the running belt.
  2. Determine the amount of AC input current being drawn by the unit under no load and loaded conditions using a clamp on AC ammeter. The current displayed can be used to determine the condition of the deck and/or running belt. These same readings should be taken on a like unit, in good operating condition with a known good deck and running belt. The readings from the unit in good operationg condition can be used as the benchmark. Compare readings and replace* the deck and/or running belt if necessary. *Some units have a reversible deck. Be sure if the deck is being flipped or replaced, a new belt is installed on the new deck surface.*
  3. Inspect and repalce both drive motor brushes if necessary.
  4. Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the filter capacitor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the filter capacitor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the filter capacitor.
  5. Measure the AC input current without a load using a clamp on AC ammeter. Electrically isolate the inductor from the drive motor circuit. The drive motor leads need be kept intact so the drive motor will operate with the inductor removed from the circuit. Re-measure the no load AC input. If the AC input current is significantly lower, replace the inductor.
  6. Swap the existing drive motor with a known good drive motor.

Ok So We Bought This. But We Have A Problem Does It Take Water Or Not? Thats What I Need To Know! Please Help!


The DeLonghi PACA120E Portable Air Conditioner quickly cools rooms up to 400 square feet and comes equipped with several functions that make operation easy and low maintenance. Its 3 operating modes are supplemented with no-drip technology, an adjustable thermostat, 24-hour timer, and much more. This unit truly takes the work out of cooling medium- to large-sized spaces. Multiple Modes and Functions The DeLonghi A120E-also known as the Delonghi Pinguino PAC A120E-offers 3 operating modes and 3 additional operating functions that make this model versatile and energy efficient. Cool Mode: 12,000 BTUs of cooling power help cool large rooms, offices, or basements. Dry Mode: Reduce room humidity by removing excess moisture from the air. Fan Mode: Circulate air to keep your room comfortable without using a lot of energy. Low, medium, high, and an auto-speed are all included (auto speed selects a fan speed for you). Smart Function: Your AC uses Cool and Fan mode based on ambient room temperature. This function will also select your fan speed and keeps your room comfortable without wasting energy. Sleep Function: Using a low fan speed, the AC gradually reduces operation so your room remains comfortable but the AC runs more quietly and efficiently while you sleep. Boost Function: This function is ideal for the summer months and uses the maximum fan speed to rapidly reduce your room temperature. Useful Features Using DeLonghi's patented no-drip technology, this unit is "dripless" under normal conditions, meaning the AC will discharge all of the moisture collected from the air-so you typically won't have to worry about draining the water. When dehumidifying a lot of moisture in Dry mode, excess water may collect in the internal collection tank. Once the tank is full, the air conditioner will automatically turn off to avoid overflow damage. You can also use the included continuous drain hose as a no-fuss way to eliminate excess water as needed. An adjustable thermostat provides additional convenience by allowing you to set your room temperature. The DeLonghi portable AC will cycle on and off to eliminate over-cooling and maintain the set temperature. Additional Features Washable Air Filter: A washable air filter helps remove allergens and other particles from incoming air and saves you money on replacement filters. Quiet Operation: High efficiency compressor and components result in quiet performance. Electronic Controls: The LCD screen displays the timer and temperature settings, while intuitive indicator lights accompany each operating mode. 24-Hour Timer: This feature lets you program your AC to turn on or off up to 24 hours in advance, so it only runs when needed. Window Bracket: Double window bracket is included with purchase for flexible installation. Self-Diagnosis System: The unit includes a self-diagnostic maintenance system that identifies malfunctions should they occur. Remote Control: Use the full-featured remote control to change modes, set the timer, and select a fan speed up to 23 feet away from the receiver (on the front of the unit). Portability: Easy-roll casters and dual carrying handles make it simple to move this model from space to space.

Problem #1:Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor.
If your motor capacitor is not the problem, then more than likely you need a new motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard to turn then you probably need a new motor. Problem #2: Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season. Some compressors just have a hard time starting after sitting all winter long. Some compressors are locked up so bad that I can not start them and must tell my customer that they need a new compressor . Many times I can get the compressor started again without having to buy a new compressor or new air conditioning system by using the device called, "Super-Boost." I keep two or three of these on the truck. They have saved many of my customers from having to buy new air conditioning systems.

Apparently, American Comfort has a plan to start selling parts and accessories online in the near future. However, if your unit is still under warranty and the only thing you have to pay for is shipping both ways, is attempting to repair it yourself really worth it?

Consider these things:

If you attempt to repair it, you void the original warranty.

The cost of parts and shipping those parts, may be equal to the cost of shipping the unit in for repair.

Your attempt to repair it yourself fails and there's no warranty on your repair. Plus, you voided the manufacturer's warranty by doing those repairs.

According to your Warranty http://www.americancomfort.com/warranty.php . American Comfort has the option of replacing the entire unit, if it's deemed appropriate, rather than repair it. Which means you get a new unit and a new warranty. Also, if they replace the pump, that part is warranted again.

With all that said, why would you not want to pay the shipping cost and do away with all the hassle?

Hi, the tech should have been able to figure the stat out with out a manual to see why the condenser is shutting off at 1:00 P.M. This is unusual for this to happen, unless it was winter and this is a heat-pump going into defrost, but just the fan would shut down. Does this unit have a box on it that was installed by your electric company that shuts the unit off during high peak conditions in the summer? This would cause it to shut down at the same time everyday. If not, it would have to be something in the thermostat that is set for it to shut off at that time. It still does not make since, as it would shut both the indoor and outdoor unit off, not just the condenser. Are you saying that just the condenser fan motor is shutting off, but the compressor continues to run until it shuts off on high head pressure when the fan stops, or does the complete outdoor unit shut down fan, compressor and all at that time??. It sounds to me like this outdoor unit has a time delay relay that has a fault in it may be shutting it off at this time daily? Please let me know if its just the condenser fan motor that shuts off, or if the complete unit is shutting off all together, this will help .
Sincerely,

Kenmore AC compressor on and off while outside unit fan running


If the out door fan keeps running and the compressor cycles off that would be the overload in the compressor.
What keeps the windings cool is the refrigerant back to the compressor.
For the overload to cycle it would have to be either not enough cooling back to the compressor or high amp draw, which could be the metering device (txv or orifice) or low on charge, or other things would be a bad capacitor, sometimes a bad start relay not staying open, when compressor gets up to speed or anything causing the compressor to draw high amps.
To check the refrigerant, he needs to check the superheat at the compressor it should be appoximately 12° to15°, and next time the compressor goes off if you shut the power off and feel the top of the compressor and if it's hot 130° or higher it's probably refrigerant.

Exhaust fan running slow


sounds like the compressor is turning off cause of high pressure. check the coil that the exhaust hose connects to, if dirty clean it. if the fan is not blowing enough air threw the coil the unit will build up high side pressure and cut out, but will turn back on when pressure drops. if that dont help, maybe the fan motor is bad or needs taken apart and oiled.
