we’ve done all of the research for you. Fortunately, if you have a basic
understanding of what the error codes signify, you can resolve the issue. It’s
time to replace it if you can’t get rid of all the filth and grease it’s
accumulated.Check all the buttons- Sometimes, buttons get stuck, So, to
correct this, push all of the controls. Here are some preventative measures
that you can take: Regular maintenance and cleaning of the air filters and
coils can prevent them from becoming blocked or dirty and causing the P4 error
code.Scheduled annual maintenance checks by a professional technician can
detect and fix any potential problems before they become major issues that
trigger the P4 error code.Prompt repair of any malfunctions or defects in the
system can prevent the problem from getting worse and causing more damage,
leading to more expensive repairs. In technical terms, the e4 error isn’t even
an error. Compare to manufactures recommendations. Over time, these coils can
become dirty or faulty, hindering the heat transfer process and causing the P4
error code.
It can also indicate a high pressure cut-out or a pipe temperature sensor
checking channel problem.A wiring mistake.Defective fan assembly.Defective fan
motor.Defective control board.To begin, inspect the wiring of the fan motor to
ensure that it is correctly connected and not loose.Note: You might think that
all manufacturers would use the same codes to make things easy for repair
shops and customers, but this isn’t the case. This guide will take you through
the top 24 common error codes of an air conditioner, what causes them, and
most importantly, how to fix these AC errors.You don’t have to be an AC or
HVAC technician to notice if your air conditioner has problems, because error
codes are displayed on the control panel.
07-12-2019, 01:02 AM #1 Went to a call today. Check for any visible signs of
leakage and charge the system with the appropriate amount of refrigerant if
needed. The only possible explanation is wrong voltage was applied, power
surge, or the wiring was mixed up. Some error codes solutions differ from one
AC model to another. To restart the unit, press the button one more time.
Checking for refrigerant leakage and charging the system Low refrigerant
levels or refrigerant leakage can cause the P4 error code to appear. Some
manufacturers require professional installation and repair services to
maintain the warranty. Reinstall it after cleaning it with soap and water and
allowing it to dry.
While my brother hooked up the outside unit I did the inside on start up fried

by pressing the “Power” button. The customer called me back Wednesday. Thanks
02-12-2021, 08:27 AM #13 No need calling tech support without being there,
thats the way it works. Air filters help to remove dirt, dust, and other
contaminants from the air, but when they become clogged, they can reduce
airflow and cause the system to malfunction. Also took amps on the compressor
and it ramps up above the water 12amps to around 17 amps before it cuts off.
Note: If you continue to have issues or cannot get the error number to remove,
contact the manufacturer for more information.If your air conditioner displays
an e2 error, it signifies a problem with the external unit sensor. I found
online its possible the valves were not opened or not all the way; had him
check that he says they are back seated (all the way open). To do so:Remove
the bottom drain cap and wait until all of the water has been emptied from the
tank.Return the cap to its original position.Check to see if the error code is
still present.A communication error code of e6 indicates that the inside unit
is unable to communicate with the outside unit.
If the panel appears to be in good condition, unplug all of the leads and
reconnect them to ensure appropriate connection.Clean the air Filter- To clean
the filter, Turn off the unit, open the front panel and remove the filter.
Haier AC models are particularly prone to this.Reset the control panel- To
reset the control panel, unplug the unit for at least one minute before
plugging it back in.Do a hard reset- Some air conditioners are designed to
display this error after a certain period of use. Dirty or Faulty Evaporator
Coils The evaporator coils in your air conditioner help to absorb heat from
the air and transfer it outside. Cleaning the air filters and evaporator coils
If the P4 error code persists, it may be due to blocked or dirty air filters
or evaporator coils. This step requires the assistance of a professional
technician. To avoid unpleasant odors, don’t use chemicals.Make sure the air
blower in your indoor unit isn’t clogged. I tried contacting Mr. Cool again
yesterday. This shows that the system has identified a leak.It indicates that
the refrigerant pressures are either excessively high or excessively low in
certain areas. The temperature should not exceed 212 degrees Fahrenheit.Look
for any signs of a refrigerant leak.Look for low refrigerant levels.Check
overload protector sensor.Examine the main PCB board for the outdoors.If your
air conditioner has a p3 error code, it simply means that the ambient
temperature outside is too low for your compressor to function.The unit has a
problem with the voltage or current.If the outdoor temperature is below -13°F
for an extended period of time while in heating mode.Blockage in the
system.Faulty wiring.If the external temperature is higher than -8°F for a few
minutes and the compressor stops, a p3 error can result.Check if the
temperature outside exceeds the air conditioner’s operating range.Check to see
if the current detecting circuit is defective; you should replace the electric
control if it is.Check the power supply voltage is normal if the problem did
not occur in standby mode.Verify that the voltage at the external terminal is
normal.Check the power lines if the voltage isn’t right.Check if it is on
standby mode because the main outdoor PCB may be faulty if the issue occurs
while the system is in standby mode.The p4 error code usually indicates an
unusual rise or drop in your system’s voltage. This applies to both high and
low voltage lines.A problem with the wires that connect the internal and
outside units.Check the voltage on the external unit first.On the inside of

situation.The specialist will inspect your system for any leaks or other
problems and provide you with a service that will involve a refrigerant top-
up.An f1 error is used by other AC systems to indicate that the indoor and
outdoor systems are unable to communicate with one another. With Mr. cool it’s
sometimes cheaper to just replace it! 02-12-2021, 08:25 AM #12 Yes, I have
only been there once. Customer says he has talked to support, he has followed
their recommendations, has had an electrician check voltage twice, (I’m not
sure if this includes the communication voltage check), has also had another
hvac contractor come out, said it was low, added refrigerant, but still
outdoor unit will not run; support has sent him the outdoor control board and
indoor board as well, none of this helped. Corrosion on connections can cause
this error, so clean each one with light abrasive paper.Check that the
connections are in the proper position. Regular maintenance, annual check-ups,
and prompt repairs can prevent the P4 error code from occurring. If there’s a
refrigerant leak or if the refrigerant charge is too low, the system won’t be
able to cool effectively and will trigger the P4 error code. Tech support said
it could be the board but I don’t think it’s that. This indicates that the
temperature sensor isn’t operating properly. If chock blocks or rotary
isolators are used, double-check that the connections are secure and that the
isolator is turned on.Contact a HVAC technician to replace both the indoor and
outdoor PCB.How to fix the f1 error on the portable air conditioner:Shut down
the machine.Ensure that the pump connector is correctly installed on the
