Hi, I'm Tim and I'm an HVAC expert here to assist you with your questions. Please provide all information I request as it makes it more difficult to troubleshoot something when I'm not there onsite. Essentially, you become my eyes and ears. Thanks for the opportunity to help. At the end of our dialog, you will have a chance to rate my service, but please wait until we are finished and you're satisfied you have all the information you need. Please be patient as many times we work with several customers at once.

What does the error message mean?

Are the condenser coils clean?

Customer: replied 11 months ago.
Those on inside?
Expert:  Tim H. replied 11 months ago.

Nope on outside unit.

Customer: replied 11 months ago.
Can we do this by phone
Customer: replied 11 months ago.
All looks clean on outside unit
Expert:  Tim H. replied 11 months ago.

Take a hose with a sprayer attachment, and starting from the top, rinse through the coils all the way down. Thoroughly clean them out. Let me know when this is done, please.

Customer: replied 11 months ago.
Actually it just started up. I reset the fuses
Customer: replied 11 months ago.
How about that
Expert:  Tim H. replied 11 months ago.

It will probably go out again if condenser coils are dirty or condenser fan is not running

Expert:  Tim H. replied 11 months ago.

Its had time to cool down.

Customer: replied 11 months ago.
Like I said everything looks clean
Customer: replied 11 months ago.
Far as I can tell
Customer: replied 11 months ago.
I'll clean them off anyway
Expert:  Tim H. replied 11 months ago.

Can't go by looks. There can be dirt trapped between the coils

Customer: replied 11 months ago.
Good to know
Customer: replied 11 months ago.
You say a hose will do it?
Expert:  Tim H. replied 11 months ago.

Hose with a sprayer attachment. Set to steady stream.

Customer: replied 11 months ago.
Ok - thanks Tim
Expert:  Tim H. replied 11 months ago.

While out there, make sure the condenser fan is running and blowing air out the top.

Let me know if you have additional questions. Otherwise, good luck! Thanks for using Just Answer and please don't forget to rate my service as that's how experts get paid (thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Even though the Just Answer site has your money on deposit, it does not get transferred to me until you (positively) rate my service. Feel free to post back with any more questions. Remember, you can rate question at any point and still ask more questions (related to the same thing) later on. Experts prefer if you rate question at the end of our first chat.
