Question about Heating & Cooling
I have a Comfort-Aire RAD-121-5-C 12000 BTU window a/c unit. It seems to work fine as far as cooling but sometimes it just shuts off, and then I can't turn it back on for at least 10-15 minutes. This can happen several times in one day. I cleaned the filter and it seemed to be working better but it is back to doing this. What could be the problem?

SOURCE: Comfort Aire PAC-121 problem
E4 shows up on the screen on my PAC-121 when the water reservoir on the right-hand-side is not pushed in all the way. If it is in all the way the switch that it engages may be bad or out of place.

actually it can be charged like a car "if" it has charging ports which it won't have unless someone has installed them - which would only of happened if the unit had a leak previously. So, to answer your question a window unit can be charged like a car but it's a little more complicated than charging a car and I would think you'd need a serviceperson to do this.
Also, if you don't have charging ports already installed on the unit - the chances that you have a leak is not very strong. These are 'sealed' units and really do not spring leaks very often.
I would be more inclined to think you had an electrical problem, i.e. wire burnt off compressor terminal or something like that instead of leak.
Sometimes you can save a lot of money and time - by getting a qualified serviceperson involved.
