I believe that my air conditioners temperature setting does not work anymore. Previously, it would stop blowing cold air depending on the temperature setting. Now, even when placed at the lowest temperature, the ac continues unless i manually turn it off myself. Please let me know how to solve this.

if it is set to 76 degrees and its 78 in the house its working fine it is suppose to shut off once it reaches 76 but sometimes there is a 1 or 2 degree differential built ini would keep you filter clean and as long as it blows out cold air i wouldnt be to concerned most airconditioners need yearly cleanings though

Possibly the unit is frozen and low on freon. Turn the unit off and put the fan off of auto to on. It should defrost! After doing this, you will need to call a professional to check to unit and recharge it with freon. If it continues to happen, there may be a leak somewhere! Good luck!

Depending on what type of Thermostat you have, it is usually as simple as setting a jumper for Electric heat instead of gas.
If you have a digital Thermostat then turn off the power to the Air handler and remove the thermostat. Look closely at the small jumpers and make sure your jumpers are set to elect. and not gas so the fan can run in heat mode.
If you have a standard heat cool mercury switch then same as before with the power and unscrew the thermostat, and where the yellow wire is connected if there is a factory with on the yellow, then move the factory wire to the (A) and put the yellow wire back on the (Y).

Good Luck!
