i turn on the air conditioner and it stuck on 75 and i can get it lower
Type of HVAC: Air Conditioner
Is it the thermostat setting that you are having a problem with? OR is your room temperature just not coming down to a lower setting?
i think both
Is the outdoor unit running?
Are you still online?
I am going to switch formats. I think the chat feature may be not working properly.
Our chat has ended, but you can still continue to ask me questions here until you are satisfied with your answer. Come back to this page to view our conversation and any other new information. What happens now? If you haven’t already done so, please rate your answer above. Or, you can reply to me using the box below.
Please explain your situation a little more.
1. Can you turn down your thermostat to a lower than 75 degree setting?
2. Once the stat is turned down, does the air conditioning unit start up and run?
i cant turn it down its stuck on 75 and its still 90
i tryed to turn the stat down but it stuck on 75
are u still there
IF the temp is 90 degrees. Then the stat not going below 75 is not the problem. You should get cooling if the stat is set anywhere below 90 degrees. Is the a/c unit running at all?
Is the air blowing out of your vents at all?
Is the air cool at all blowing out of the vents?
Please answer these, then we can continue trouble shooting.
yes the a/c unit is running and cool air is running some what
Ok, the first thing to check is your Air Filter, Make certain that is clean and free flowing. Also if you look at the large copper line going into the Furnace, from outside, it should have foam insulation around it. If you were to pull back the insulation a little by the furnace, and feel it, is it very cold and wet? or is it just a little cool? or is there ice on it?
i just strayed the filter yesterday and it is clean, but i just dont understand why the stat is stuck on 75, before this happened i would put it down to 70 and it would go down to 70 and cool air would come out and cool the house in minutes and now i cant get its down from 75 and little cool air is coming out and downing nothing cause its been on for about all most 2 hours and its is on 90
I am trying to find out if you have a problem with your thermostat, not turning on the compressor, I think you may have something wrong with the Air Conditioner, but it could be the thermostat. Can you tell me about the line temperatures? I need to know if the compressor outside is actually functioning. If you have a jumper wire, we can by pass the thermostat if need be, but feeling the large copper line and reporting this finding of the temperature of this line would be helpful.
i checked out side and i dont think it on
didnt see any ice on the pipe, and they were not cold
Ok, if the outdoor unit is not running, then this is good information. Is the outdoor fan running? It should be very obvious if it is on or not on. Please check your breaker for the ac unit in the breaker panel. Turn the breaker off completely then on again. Then check to see if the outdoor unit comes on.
the unit is running but the fans arent
If you found that the breaker was tripped, and the compressor is just turning on, there could be a slight delay before the fan turns on. If the fan does not turn on, then the compressor will run for a short time before kicking off because of high limit.
If the fan outdoor does not ever kick on, then you will need to check the capacitor at the outdoor unit. It may be faulty. Or the fan itself may be bad. Does the fan seem to spin freely if you were to use a ruler or other thin stick to reach in and manually spin the fan?
the fan spins freely, the breaker wasnt tripped. i pulled out the fuses and stuck them back in and went to check on the breaker, heard on noise went to check on it and the unit was on but the fan didnt come on
Ok, I think we have determined that the problem is not in the thermostat, since it is telling the outdoor unit to come on. The problem is the fan on the outdoor unit is not working, either because of a bad fan motor, or a bad capacitor. Do you have an electrical tester, and the ability to trouble shoot this further? Either way, this is going to require some parts to install. Let me know if you are comfortable in proceeding, or if you would rather call in a service tech for this.
now the thermostat is on 80 and i cant more it. i think some one lock it to a program, is there any way to change the program
What model is the thermostat?
I will need to know the model number. Luxpro is the brand and they make many different model numbers. You may have to remove the front cover from the thermostat and look at the inside to get the model number.
You can look on this page to match up which of these best fits the style of your thermostat, if you can not find a model number.

looks like psp600
I have downloaded an read the instructions for this model.
I find nothing out of the ordinary here about this thermostat. It does appear that the stat is discontinued however. You may be best suited to replace the thermostat if you are having problems with setting the temperature to a low enough setting. You can remove the cover and put a jumper wire between the yellow and rc terminals, and this should turn on the cooling in your home for testing. You still have a problem with the outdoor unit not coming on. The only other recommendation I would have at this point would be to remove the batteries, and turn off the breaker to your furnace. Then reinstall the batteries and turn the breaker back on. This should reset the thermostat to the original programming.
ok well im done, got to go to bed. thought this was a long shot but we tryed
One other thing I just thought of. .. Turn your thermostat to the heat mode. Then adjust your set temperature down as low as it will go. Then turn it back to the cool mode to see if it will allow you to adjust the setting lower. This will not fix the outdoor unit problem, but may be the problem that is not allowing you to turn the unit down lower in cooling mode.
