Air conditioner
Asked by GuruTMDW5 Jul 21, 2018 at 08:00 AM about the 2014 Honda Accord LX
Question type: Maintenance & Repair
I have a honda accord 2014 4 cylinder and the air conditioner compressor just
started to turn on and off every 15 seconds or so but still blows cold air. What
are some potential causes? A relay switch or low freon level?

That frequent cycling of the compressor is a classic symptom of a low charge. (Your low pressure protection switch is getting tripped.) Your vehicle is fairly new so if nothing else is happening, you just have to get the charge topped off. It is a very good sign that it is still blowing some cold air.
Thanks for the response!
From my prior question on the air compressor cycling on and off every 15 seconds and following the suggestion of topping off the refrigerant since it was still blowing pretty cold air during the 15 second cycling: I added 3/4 of a 16 oz container of R134a and it still cycles every 15 seconds on and off but really keeps the car frosty to the point the windows start building condensate up on them at 75 degrees outside temp. The guage on the 16 oz can of refrigerant (Supertech brand name) reads on the low end of the pressure guage of 25 psi (right on the green/blue line) when the compressor is engaged. Green is the zone to add refrigerant. When the compressor stops the guage goes to just under 45 psi. I do not want to over fill it but if it is still reading close to 25 psi on the border line low end when the compressor is running and still cylcing every 15 seconds on the dot should I keep adding refrigerant? I sprayed soapy water on hose connections that I could get to readily and did not see any leaks this way.
Hi GuruTMDW5, did you ever solved your problem? I have the same issue with my 2006 Odyssey. Gauge charge pressure seems to be okay.

It appears you have added enough refrigerant to correct the low charge condition. It doesn't take much when the whole system holds only two 16 ounce cans. Your high pressure limit switch will also cycle the compressor off if the pressure goes too high in hot weather or an overcharge. The cabin thermostat can also cycle the compressor on the medium settings. I hope I haven't confused you with too much info. If your recharge gauge says it full, then you are good. Best time to service these is in hot weather.
