Friedrich CP24F30 money saver mode not working


Money saver mode dose not regulate room temperature. All that mode dose cycle fan on and off with the thermostat if in the yes position then fan cuts on and off with the call for cool. if in the no position than fan runs all the time even when cool is not needed. that switch is like the auto/on on a thermostat for central air. the thermostat is what regulates temp in room.

Tip

Keeping your whole home cool with central air.


Sometimes it is difficult to keep your home cool in the hot summer months. Also, some areas of your home may still be hot where other areas are too cool. Try this method to keep your home cool evenly throughout. Before you get started make sure your furnace filter is new. This will allow for maximum air flow.

If your living space is a single floor plan:

  1. Turn the air conditioning on
  2. Switch the furnace fan from auto to on.
  3. Measure the temperature in each room.
  4. Close the vents by about half in the cooler rooms
  5. This will force more cool air into the warmer rooms.
  6. Keep adjusting the vents until all the rooms have the same temp.

If your living space is on more than one level:

  1. Turn on the air conditioning.
  2. Switch the furnace fan from auto to on.
  3. On the lowest level of the house close half of the vents that are the closest to the stairs.
  4. This will force more cool air to the top floor where it is usually hotter.
  5. Cool air will sink from the upper floors which will keep the area near the stairs cool.
  6. Measure the temperature in all the rooms.
  7. Keep adjusting the vents until you have a nice even temperature throughout the house.
I found that leaving the furnace fan on all the time will keep your home evenly cool and comfortable. You may have to replace your furnace filter once a month due to the increased air flow. It will be well worth it in a cooler, more comfortable, and more energy efficient home.

Take Care,

Hi, I have a Friedrich air conditioner. Old one I am pretty sure. Maybe 9 years. Model is SL28J30A-D. I have a feeling my filter is not working properly or I don't even have the right one in. Currently I...


The evaporator coil (cold coil) would freeze up if the air entering is restricted. It could shut down because the rear coil (condenser coil) is dirty or obstructed. Sometimes there's debris or even bird's nest blocking the condenser air outlet, this causes heat and high head pressure.

My friedrich quietmaster does not turn on but touchpad turns on


If you are using A/C in cold weather. If there was water in base pan, the condenser fan blade might be frozen in ice. You would need to slide the chassis out 1/2 way out of sleeve to check rear condensor blade.

My Friedrich A/C is turning on and off by itself, can you help me?


when the room reaches the set temperature the unit is made to cut off until heating or cooling is needed again, this is the units way of not cooling or heating too much.

Unit not cooling house below 80 HELP ME PLEASE


It's 98 outside ... that says a lot. The gurgling is an indication that you are getting a lot of water out of the air (dehumidifying). If the unit is sized just right, or just a little too small, it may be working perfectly well.

You don't say where you are, geographically, but much to the US has an air conditioning design temperature of 95 degrees F. That means at 95 degrees, the unit will run continuously. With a 50% outside air relative humidity, it should keep the occupied space at about 75 degrees F. The more humid the air, the more the unit works on dehumidifying and less on cooling.

Give it some time, wait unti the weather breaks and see if it doesn't run just like it used to. If you chose to call a technician, have him/her take temperature readings of the condenser entering and leaving air, the suction line temperature, the liquid line temperature, the inside supply and return air temperature (dry bulb and wet bulb) as well as high and low side refrigerant pressures. Before they make ANY changes to the system (refrigerant charge) have them explain what they found wrong and make sure you understand what they are talking about. Adjusting the charge under these conditions, will mess up your operation under normal conditions.

Shut the power off to the unit, spin the fan blade to see if it spins freely. If it doesn't spin freely, (there appears to be a little drag when you spin it),the bearings are bad, if it does spin freely, then try moving the motor shaft from side to side if there’s any play in the shaft side to side then the bearings are worn and motor needs replaced. Then, check the capacitor, if it’s bulging even slightly, the capacitor is bad and needs replaced. Most of the time people replace the capacitor if motor seems ok. If capacitor is ok, turn power on to see if the motor is getting the proper voltage, if it is and not trying to run, then the windings are probably open, the motor's bad and needs replaced.

Squealing and sometimes doesn't blow cool


A squealing noise is most likely the bearings going bad in the blower motor. This will slow the motor down. If the blower is not operating at the proper speed this will affect the temperature pressure relationship of the refrigerant. This will cause the unit to put out the wrong temperature. Running the unit to long under these conditions can possibly cause further problems ( including a very high electric bill). I recommend that use do not use this unit untill it is repaired or replaced.
Good luck.....
