Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
OK there are three things that I need you to check for me - a. Is the fan going around inside the unit, b. when it is running is there any frost on the finned cooling coils c. can you touch the motor ?
IT is a sealed unit . I have no access to the fan or the cooling coils
I have now to leave and cannot return until this pm
You should be able to hear/see the fan spinning and the coils will be available through the front or the back cowls.
