Question about Friedrich QuietMaster Deluxe RS12L10 Air Conditioner

1 Answer

Friedrich QuietMaster SS12H10

The fuse/breaker blows when I turn on the unit. After I turn on the unit it makes a low humming noise for about 2 mins then the circuit breaker blows. The unit is on the same electrical outlet as it was last year, and the fuse did not blow last year.

    I was afraid that might be the solution. I inherited this unit with the apartment, I have no idea how many btu's it is or how to replace it since its a window model and I guess was fitted especially for the window it is in. I have the manual but even it doesn't answer how many btu's (terminology ??) the unit is.

It is probably either the Compressor and or the capacitor that has failed. The compressor will hum and pull a lot of amps when it has seized up. Sounds like it is time for a new unit.

    I believe that this unit is a 12,000 btu per hour.

    New units usually come with the necessary components to mount in an average size window. In the case that the package does not come with all that you need. A salesman at the store of your choice will make sure that you get all of the right equipment that you need.

    I wish I could be of more help for you. Unfortunately I am not sure what pieces will come in your kit. If you luck out the old brackets may match right up to the new ones. If they do not. Then just read the directions carefully and you will do just fine. The installation is usually pretty painless if the dimensions are the same.

If you are using A/C in cold weather. If there was water in base pan, the condenser fan blade might be frozen in ice. You would need to slide the chassis out 1/2 way out of sleeve to check rear condensor blade.

Yes the northeast had temps that went past the limits of modern a/c.
Try cleaning the outside fins and coils.
Spray a product called simple green on the fins while unit is off.Leave on for 5 min.
Then rinse off with a hose.
This should keep your compressor running cooler.Also clean any filters in the inside unit.

How to remove front cover for cleaning

I don't know too much about your particular make / model but most window units have a 1 piece front cover which is usually held on to the main cabinet with 1 or 2 screws at the sides and 1 or 2 behind the filter panel. You will need to remove the front panel to remove the vents as they are usually fitted from behind the panel.
