New AC thermostat setting creeps up when running the Timer Mode

I turn the unit on and set it to 74. After I turn on the timer it goes up to 76-78 within an hour or two. I haven't had it more than a week.

First check the following first.
1. Keep the temp between 24 to 20 degree celcious
2. Check the air filters are cleaned
3. Check the power is correct.. if there is fluctuvation use stabiliser or booster
4. Check condensor coil is cleaned.

Conclusion. Every a/c must be cleaned once in 3 months and air filters are to be cleaned by every week.

On a Friedrich in wall AC/Heater in the heat mode in the digital display while the unit is working fine I get a flashing 08 alternating with the temp of 74. Model # PDE15K5SB-A is this a trouble code

This is an error code for "Unit cycles more than 9 times per hour". The service manual says the possible causes are "Unit oversized" and "Low load conditions".

1) If the OUTDOOR A/C Condensing Unit is running BUT the indoor AIR HANDLER is NOT running, the problem could be as easy as changing the RUN CAPACITOR which is usually located within very close proximity of your indoor air handler motor. Ensure the ELECTRICAL DISCONNECT SWITCH is "OFF" and change the oval run capacitor (usually a 5 microfarad capacitor). This SHOULD fix your problem.

2) If the OUTDOOR A/C Condensing Unit is NOT running BUT the indoor AIR HANDLER is running, the problem could be as easy as the outdoor unit is not receiving the required 220 Volts AC. Turn the circuit breaker for the A/C Unit OFF and then turn it back ON. Ensure the circuit breaker SNAPS when you turn it to the ON position.

3) If the previous two steps to not apply or do not work, go to the paperwork supplied with the Thermostat. Almost every manufacturer provided a TROUBLESHOOTING GUIDE within their literature. Follow those steps. If their TROUBLESHOOTING GUIDE does NOT fix your problem, they should have a TOLL-FREE TELEPHONE NUMBER provided to contact their TECHNICAL EXPERTS with your problem(s). Call them and ask them what could be causing the problem.

Setting timer on window unit to turn on and off

Hi Jessica Yacopino - Generally speaking, Frigidaire air conditioners timer option typically have the same procedure. The unit must be in the ON position for the timer delay stop option. For delay start, the unit must be in the OFF position. First, press time button. Then to adjust timer setting, tap or hold the UP arrow or the DOWN arrow to change delay timer at .5 hour increments, up to 10 hours, then by 1 hour increments up to 24 hours. The control will count down the time remaining until start (8, 7.5, 7, etc.). The Delay Start mode automatically selects cooling with maximum Fan Speed. The temperature maintained will be the same as previously set. To change the set temperature, press "COOL" then Up or Down arrows until the desired temperature is indicated on the display. After 5 seconds, the control will automatically change the display back to the hours remaining until the unit will start/stop. PRESSING the unit On/Off button at any time will cancel the Delay Start/Stop function. The Delay Start/Stop Feature will work until the unit either starts or stops. Once that happens the above steps have to be repeated again.

How to set timer

Switch on a/c by remote.Keep mode and set temp as you need. Now press timer on button. In some unit it follows on clock. and some units it follows time starting. That is if you need to start after one hour you have to press timer still 01.00. Same way to timer off also.

My A/C unit was working fine but I turned it up for an hour or so while we were painting and the doors were open. Since I have turned it back down it will not blow cold air. What could have happened?

once you turn your unit down it will blow just the fan till it calls for cool air again . like for example if you have your unit at 68 & you turn it up to 73 your unit want call for cool air till it reach 74 , then it will work till it has met the coolin stage and it will blow fan again unit it reach 74 and it will do the same thing .. i hope this is just the only thing that is wrong and that is just the only problem you have ... see if this works for you.....

It making a humming sound and the fan is going around slow the temp in home is 74 the set temp is 65 so it should not be running what could be the problem ruud upka-035jak is model

If you are running A.C.,and the T-stat is set at 65,and the room temp is 74,the A.C. will run until the temp goes down to about 65 or so.Turn T-stat to 76 and the unit should shut down. Also,check furnace filter for dirt, and check condensor unit coils and see if they are dirty.If condensor coil is dirty it cannot breathe properly. That will cause the compressor, and the blower motor to overheat.Wash cond. coil down with water hose to clean .Start at top of coil and go sideways,slowly going down.

I have a york hvac system that is 5 years old. I have the thermostat set at 74 and when it turns on only the fan runs circulating the existing air in the house about 20 percent of the time. The a\c works...

It sounds to me like you have a delay on start timer on the compressor that possibly is starting to fail or someone may have adjusted the time band up on it. I myself would remove it and install a delay on break timer and a 5 minute setting would be ample time.

Hope this helps Ya
