[eritech1]

Do u mean FH1-SSB-HD?

you can refer to the service manual by downloading it from parts town, for some reason I can’t attach link.

E4 is a high pressure alarm.

It means that the condenser is running to hot.  There-by overloading the compressor. 

 

Remove the air filter and wash it.  Clean your condenser and make sure the fan is operating at speed and moving air.  Also that it has the proper clearance from the wall and nothing is on the top. Note clearances and max temp for operation. With the nation’s high temps this past week, Marginal installs will have problems.

In case you have misplaced your manual:

This also has a effect on your problem.

eritech1, in the gray bar at the top of your comment there is a image of a chain link.  Just left of the camera.  Copy your link and click the chain.  It will open a window with a linc location that you can paste in.
