Troubleshooting your °CoolBot 

Sensors Calibration Test

If you suspect there is a problem with one of your temperature sensors (Room or Fins), there is a simple procedure to make sure they are working correctly.

Applies to all CoolBots where the cables plug in at the bottom.

Heater Cable Test

If you suspect there is a problem with the Heater Cable there is a simple procedure to make sure it is warming up.

A heater light pulsing slowly is completely normal! That means the CoolBot is trying to keep the Heater Cable warm to “fool” the A/C’s temperature sensor and cool the room.

  • Heater light pulsing slowly (or ON) = CoolBot is calling for Cool
  • Heater light OFF = CoolBot is on a Defrost Cycle OR has reached Room Temperature Setting

Remember! The Heater Cable is NOT for defrosting the A/C. Its only function is to warm the temperature sensor of your A/C (to “fool it”) so the compressor stays on and the room can cool.

Applies to all CoolBots where the cables plug in at the bottom.

Er error - Room light flashing

If your CoolBot is displaying a permanent Er error on the screen and the Room light flashes rapidly there is a problem with the Room Sensor Cable.

Applies to all CoolBots where the cables plug in at the bottom.

Ef/Er error - Fins light flashing

If your CoolBot is displaying an Ef (Er) error intermittently with a number (room temperature) and the Fins light flashes rapidly there is a problem with the Fins Sensor Cable.

Applies to all CoolBots where the cables plug in at the bottom.

Workaround Mode - Bad sensor

If your CoolBot has a bad Room Sensor Cable or a bad Fins Sensor Cable, you can still use your CoolBot. This is a temporary set-up that will work OK until your replacement sensor arrives.

Applies to all CoolBots where the cables plug in at the bottom.

Factory Reset

Do this if you want to set your CoolBot to “Out of the box” settings.

WARNING! This will clear all changes you have made!

NOTE: Sometimes, when new sensors are installed you can still get an error displaying on the CoolBot, do a Factory Reset to clear any errors on the board.

Applies to all CoolBots where the cables plug in at the bottom.

ATTENTION CoolBot Pro users! There are 2 ways to do a Factory Reset on the Pro:

  • P1 or FR will clear everything INCLUDING your WiFi configuration
  • CS will just clear the CoolBot Settings but will leave your WiFi configuration intact.

Eh error - Heater cable

If you have an Eh displaying on the CoolBot you may have a problem with the Heater Cable or the heater port.

Applies to all CoolBots where the cables plug in at the bottom.

Changing from °F to °C

Applies to all CoolBots where the cables plug in at the bottom.

Troubleshooting your Air Conditioner

Cleaning Your A/C

Like any other refrigeration system and/or HVAC system, regular cleaning of your A/C is necessary and highly recommended.

Cleaning your Air Conditioner should be a vital part of your cooler maintenance plan – it will save you lots of headaches!

A dirty coil on the inside of the cooler can create many unintended issues – freezing, high temperatures, high humidity, etc. Ensure that you have a scheduled maintenance plan in place for cleaning the inside coil of your A/C. Recommended to be done at least once a month.

A dirty outside coil and motors on your A/C can lead to premature failure, overheated compressor, loss of efficiency, poor cooling performance, poor ventilation and all sorts of unintended issues.  Ensure that you have a scheduled maintenance plan in place for cleaning the outside coil and outside components of your A/C. Recommended to be done at least once a year*

*There are many videos available on “YouTube” explaining how to do a deep cleaning of your A/C by removing it from the wall and placing it on a working bench. Caution should always be used when cleaning A/Cs as to not splash any water in its electronic components or use the wrong type of cleaners. Use common sense! If using a professional Coil Cleaner available at most hardware stores, please follow the manufacturer’s recommendations. 

Watch Video on Cleaning the Inside Fins of Your A/C

Diagnose Air Conditioner Issues

Air Conditioners with Secondary Sensors

Most brands of A/Cs have secondary sensors especially if they are larger than 10K.

Window LG air conditioners that are  LW####ER Models DO NOT have secondary sensors. HAIER A/C units also don’t have secondary sensors.

All other brands are very likely to have one and it will depend on the model. Best way to find out? Just look for it or look at the wiring diagram of the A/C if it was included with the documentation.
