Window Air Conditioner: Won't start If the window air conditioner has electrical power—the control panel powers up—but the compressor and fans won't run, possible causes include an electronic control failure or a wiring problem. The window air conditioner also won’t start if the electronic control detects a component problem such as a defective thermistor. Check the control panel for an error code, which usually indicates which component failed. To decipher an error code, check our error code tables or refer to your owner’s manual. Some repairs that could correct the problem are listed below. These repairs may help solve your Window Air Conditioner problem: Replace the window air conditioner control thermostat Some window air conditioners have an electro-mechanical thermostat instead of an electronic control board to control the on/off cycling of the compressor and fans. Replace the thermostat if it fails to control the compressor and fans properly. Replace the window air conditioner electronic control board

The electronic control board regulates the compressor, evaporator fan and condenser fan in the window air conditioner. If the electronic control board doesn’t activate those components properly, replace the control board. How to Replace an Electronic Control Board in a Window Air Conditioner Replace the window air conditioner user interface control board The user interface control board in the control panel houses the selection buttons you push. A wire harness connects the user interface control board to the control board. If the selection buttons don’t respond when you push them, replace the user interface control board. How to Replace a User Interface Control Board in a Window Air Conditioner Replace the window air conditioner ambient thermistor The window air conditioner ambient thermistor—also known as a temperature sensor—senses the temperature of the air entering the air conditioner and communicates that temperature to the electronic control board, which cycles the compressor on and off to maintain the set room temperature.

The ambient thermistor is attached to the evaporator coil that’s behind the air filter, and a wire harness connects the ambient thermistor to the electronic control board. If the ambient thermistor is defective, the electronic control board will not cycle the compressor on and off properly to maintain the room temperature that is set on the control. Replace the ambient thermistor if it doesn’t accurately measure the ambient room temperature.

This wouldn’t usually be a problem, except that I am having major air conditioning problems in the office. We occupy a smaller office building where the air conditioning and heating is controlled by three panels located around the office where you can set the temperature.

My problem is that, for whatever reason, my office is always a few degrees hotter than everyone else’s, including the boss’. The standard setting it is on now means that I have a constant sheen of sweat over me while at work and I’m finding it incredibly difficult to concentrate. how central ac units workMy argument is that surely it is better for them to be cold, and bring a cardigan or jumper to work, than for me to be sweating.price for a ac unit It’s getting to the point where it is affecting my performance. best way to cover acHow do I raise this with my boss? My off-hand remarks to the Office Manager and other people have not been listened to, and are usually countered with a “Really? A friend suggested I bring a fan into my office, but I thought that might be too passive-aggressive.

I’m the most junior lawyer at my office, and I’ve been here 3 years. Given how contentious temperature control issues can be, I’m kind of amazed that this the first question I’ve received about them in nearly five years of writing this blog.I hate, hate, hate being hot, and I agree that it’s easier to warm up when you’re cold than to cool down when you’re hot. However, the majority usually rules on these kinds of issues — and especially so when you have a solution that you haven’t tried yet:  Bring in a fan, the most high-powered one you can find. There’s nothing passive-aggressive or otherwise weird about doing that; If the fan isn’t sufficient and you have a window, try a window-mounted air-conditioning unit. That was the only thing that saved me from heatstroke at my last job. But if that doesn’t solve the problem and your colleagues aren’t willing to compromise, you need to do more than “off-handed remarks.” You need to actually have a serious conversation with whoever controls the temperature and explain that it’s affecting your ability to focus.

One more thought: Can you ask about switching offices with someone who tends to be colder and would appreciate the sauna-like environs of your office?Portable air conditioners vs window unitsAAPortable air conditioners sound like an easy solution for cooling a room that can't accommodate a window air conditioner, but many are returned by unhappy customers. So Consumer Reports tested 8 from Honeywell, Haier, Frigidaire and Sunpentown, ranging in price from $250 to more than $500.Consumer Reports used a special chamber to test their cooling power. The temperature outside is kept at 90 degrees, the humidity at 70 percent. Inside, each air conditioner is set to 75 degrees. Strings of thermocouples record temperatures throughout the room. The results were disappointing. None of the units, not even the biggest ones, could get the test chamber below 80 degrees even after an hour and forty minutes.That was true even of the most expensive unit tested - the $550 Honeywell MM14CCS, which promises it "cools up to 550 square feet."
