An E4 error code on your 45 model tankless water heater, indicates that there is an issue involving the flow meter sensor (also referred to as cold water temperature sensor.) This means that the flow meter is not sending a signal to the computer which starts the machine.
Possible broken wire, poor connection or faulty sensor.
Please recheck the error code. Are you sure the code is P4 and not F4? Carrier does not list a P4 but it does list an F4 error code. F4 means outdoor mid-coil temperature sensor malfunction. Or how about E4? E4 means compressor discharge high temperature protection.
Hi Cherisse - This is a typical error code for a faulty thermister (also shows up as open contactor). On some Carrier units, it also refers to DC Fan protection...
This does not sound like a user fixable item...please contact an HVAC repair shop.
Estelle, Estelle. Learn to use Google or some other search engine. That is what they are for. Lets try "aircon manual" but you probably need the model number, right?
So, using the information you gave, I got this: Product documentation and of course it lists several models.
Don't EVER submit a question without Make and Model included, unless you want non-helpful answers.
Here are the SoleusAir error codes...
e2 Room temperature outside of working range of unit (too cold).
e3 Faulty coils - Repairs needed.
e4 Internal frost in the unit - Defrost.
e5 General failure - repair needed.
e7 Reservoir full - Empty the reservoir.
If the unit is freezing up (frosting) you may want to check (clean / replace) the filters.
The e4 that displays on your air condition come up simply because there is an error during the operation of the system. E4 means Error 4 which is a code that is interpreted as low pressure switch.
E4 simply means there is low pressure switch, the pressure switch turns on automatically inside the air condition, so when you turn it on sometimes the switch jams and does not open so the air condition will be on but would not get cold because the switch jammed and it displays an error signal to let you know there is a problem in the system.
