What to do if my Kenmore Air Conditioner is not cooling and there's ice behind the front panel?

  Wendy SanchezAug 21, 2025
  If your Kenmore Air Conditioner isn't cooling the room and there's ice behind the front panel, it could be due to several reasons. If the outside temperature is below 60°F, set the mode to FAN ONLY and the fan speed to the fastest setting to defrost the coil. A dirty filter can also cause this issue, so open the front panel, remove the filter, rinse or vacuum it, replace it, and close the panel. Finally, the BTU size of the unit might be too large for the room; in this case, a lower capacity unit may be required.

  If the remote isn't operating your Kenmore Air Conditioner, first verify that the batteries are installed properly. The remote may not work properly if used at extreme angles to the front of the unit.

What to do if water is dripping from my Kenmore 253.70121 Air Conditioner inside the room?

  If water is dripping from your Kenmore Air Conditioner inside the room, it's likely that the unit isn't properly installed. Ensure the unit is mounted on a downward slope to the outside (1/2 bubble on a carpenter’s level) to provide proper drainage. Reposition or shim the cabinet as necessary, but do not drill the drain pan.

What to do if Kenmore 253.70121 keeps blowing fuses or tripping the circuit breaker?
- S
  Sara CollinsSep 1, 2025
  If your Kenmore Air Conditioner is blowing fuses or tripping the circuit breaker, replace the fuse with a time delay type or reset the circuit breaker. Avoid using too many electrical devices on the same circuit by unplugging or relocating some of them. If your unit is rated over 7.5 amps, plug it into a single circuit outlet. Avoid using an extension cord. If the unit was turned off and on too quickly, turn it off and wait 3 minutes before restarting.

Why does my Kenmore 253.70121 Air Conditioner turn on and off by itself?
- T
  tammy85Sep 5, 2025
  If your Kenmore Air Conditioner is turning on and off by itself, it might be due to a few reasons. If the outside temperature is extremely hot, set the fan speed at the fastest setting for maximum cooling. If the ENERGY SAVER feature is on, note that it doesn't circulate air continually; set the mode to COOL for constant air circulation. Also, check if the timer turned the unit ON or shut it OFF; push the ON/OFF Button to turn the unit ON or OFF.

Why does my Kenmore 253.70121 run too much?
- Q
  qmartinezSep 8, 2025
  If your Kenmore Air Conditioner runs too much, it could be because the Energy Saver mode is selected, which causes the inside blower to continue operating for one minute to use as much cooling as possible. Also, if your current unit replaced an older one, the newer, higher efficiency air conditioner may run longer to cool the room, but the total energy consumption is less. Finally, if the BTU size is too small, a higher capacity unit may be required.

  If your Kenmore Air Conditioner isn't turning on, there are several potential causes. First, ensure the power cord is firmly plugged into a working wall outlet. Check your house fuse or circuit breaker and replace the fuse or reset the breaker if needed. Make sure the unit is turned ON by pushing the ON/OFF button. If the temperature setting is warmer than the room temperature, adjust it to a lower setting. Note that there's a built-in delay that prevents the compressor from starting for 3 minutes if the unit was recently turned off and on. Also, check if the timer has shut the unit off and push the ON/OFF button to turn it back on. Finally, if the touch pad and remote aren't responding, unplug the unit for 10 seconds and plug it back in to reset the controls. If the power cord has tripped...

Why is my Kenmore 253.70121 not cooling the room, and there is no ice behind the front panel?

  William DavisNov 16, 2025
  If your Kenmore Air Conditioner isn't cooling the room, but there's no ice behind the front panel, start by checking the filter. Open the front panel, remove the filter, and rinse or vacuum it before replacing it and closing the panel. Ensure that the temperature setting is not warmer than the room temperature by setting it to a lower level. Note that the unit isn't designed to cool if the room temperature is below 60°F. Check that the front and back of the unit are not blocked by furniture, drapes, blinds, leaves, dirt, or branches. Make sure doors, windows, and registers are closed. If you've recently turned on the unit, allow it time to cool the room. If the temperature sensor is touching the coil, open the front panel, remove the filter, turn the end of the temperature sensor away from...
