Why cools the ac only 1 hour full power and never reaches the set-point temperature ?


check that all the doors and windows are closed as ac units do not work well when trying to cool the world
is the ac unit too small for the room size
I suspect that because it is working the problem is outside the ac control
is the inside fan working and blowing out cold air

Tip

Toyota Air Conditioners


This tip pertains to maximizing the cooling efficiency from your Toyota's Air Conditioning system.

(The info that follows is for vehicles that are not equipped with "Auto" AC.)

On really warm days, nothing is better than getting in a hot vehicle, and turning on the AC for a nice comfortable driving experience.

In our service facility, we continually see customers who are not totally satisfied with their AC output. Hopefully, this tip will address those issues, and just might be useful to you.

The number one reason for poor cooling with the AC on, is neglecting to select the "Recirculate" function on the heater/AC control panel.

What is Recirculate?
That mode is where the AC system 'recirculates' the air contained in the car, thru the AC box, over and over, until the desired temperature is reached. The Recirculate button, knob, lever or slide is easily identified by seeing a picture of a little car, with an arrow doing a 'U-Turn" inside the car. This is the opposite of the "Fresh" mode, which is an arrow going 'straight through' the little car icon.

If you are using the "Fresh" mode, you are actually admitting ambient air into the car. Ambient air is much warmer, and makes the AC work harder, and you will see a 10 degree rise in the air temperature from the dash vents. Also, some vehicles admit the 'Fresh' air from under the hood, so, leaving the 'Fresh' mode selected could actually draw in the much hotter underhood air into the AC system.

So, what to do? Anytime you use the AC, please verify that the Recirculate function has been selected. As stated above, this uses the air in the car over and over, and your cooling efficiency will be 10 degrees colder. You can easily check and verify this with an 'instant-read' thermometer. Put the thermometer in the center dash vent, start up the car, turn on the AC, select Recirculate, and watch the temperature drop. It should stop dropping around 34-36 degrees F (depending on humidity, sun load, and a few other things). Now, when the temperature is as low as it will reach, turn off the Recirculate device. You will see the temperature actually rise, maybe 10-12 degrees.

Some additional info: As long as the car is in Recirculate mode, the AC compressor will eventually turn off, when the interior makes the selected temperature. This saves you gas. If you run the AC with the fresh mode selected, the AC compressor runs all of the time. This wastes gas, and costs you more money.

The best way I can easily sum up Fresh versus Recirculate is this:

Running the car with 'Fresh' selected is like running your refrigerator with the door open. It works, but it does not work good. Choosing 'Recirculate' is like running the fridge with the door closed.
If this tip helps you, please leave a positive helpful rating. Thanks!

My AC gets automatically turn it off and flashing timer bulb.


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.

this thermostat does not have a deadband option, the only other thing you can do is set the program for a different temp. the cycles per hour just restrict how many times the unit comes on.

Temp problem. freezer temp 0 deg. fresh food 46 deg.


An hour aint enough. Turn off fridge, use blow drier, thers a huge ice cube behind that sheetmetal wall back of freezer inside wall, it takes 48 hours at 75 degrees to let it do itself. Listen for inside motor, its obvious. If so, you hve a defrost problem.
