Hello and thank you for using this service.


The P4 code is a condenser fan fault. The condenser fan is located on the outside unit and cools the condenser. The fan motor could be bad or you could have a faulty capacitor for the fan. You can check the fan out depending on your skill level. Check if it is seized up or trying to run, but can not. You may need a check to do this as it can be involved if you are very handy.
