Air conitioner started to automatically climb in temperature, we shut the unit off, put new batteries in the remote. the uit will not turn on at all. Prior to this the unit worked perfectly. Can you...
Since it was running (although not cooling) when you turned it off (and put batteries in the remote) it would be strange to have no power at the outlet - but I would check and make sure.
The easy way to check your outlet is - toplug something else in there - like a hair dryer or a lamp - 'assuming' your unit plugs into a regular household outlet, and is indeed a 110 volt appliance.
Step 1 - plug another appliance (hair dryer or lamp) into the outlet
If - after plugging something else into the outlet, i.e. a hairdryer and it works ok - you will - then know that there is nothing wrong with your power supply (110volt outlet). So you can move on to Step 2
Note: if the other appliance does not work - then you need to check the Circuit Breaker to see if it's tripped off. Many times circuit breakers will trip for no particular reason and just needs to be reset (turning breaker off and back on). If you find the breaker is tripped - and you reset it - and the unit - runs and cools ok - I would just keep an eye on it for a few days - watching to see if it does again. A breaker that "keeps" tripping for no apparant reason is an indicator of something electrically wrong within the unit and probably needs a Service Tech to troubleshoot it.
Step 2 - Since the power supply is ok - see if you can start the AC manually - without using the remote. If the unit will not start "manually" - I would look for a "reset button/switch" (*not all units have one) and reset it. Note: if after resetting the unit - it still does not run then proceed to next step (step 3). Or if you can't find a reset button I would look in my manual and see if it can help you find it - if, however you do not have a 'reset button/or can't locate one' then go to next step (step 3).
If - however, after resetting - "the unit comes on and -runs and cools- ok" - I would then 'turn it off,' and let it set for 5 minutes and then try operating it with the remote. If it works with the remote I would then assume you just had an 'electrical glitch' and everything should be ok. If it "doesn't work" with remote I would suspect a defective remote and replace it.
Step 3 - since you have power (at the outlet) and either have 'reset' the unit or can't locate a reset button, or there is no reset on the unit - you are now in need of a Service Tech to electrically trouble-shoot the unit to find the problem. Note: I'm assuming at this point 'Nothing' is running, - not the fan motor - or the compressor, in which case you might look for a "fuse" in the unit - again not all units have one, indeed most do not, but it's something you could check, and easily replace if it's bad.
If, after completing all the checks above and the unit still fails to come on (either manually or with remote) - then you are, as I said above, in need of a Service Tech.
hope this has helped
