Braemar ducted air conditioning turns itself on and cannot turn off

The unit is the older model that doesn't have a remote. You have to press the button on the wall unit. Lately it started to turn itself on and then after a few minutes it turned itself off. But today it turned itself on and keep going. We tried to turn it off at the wall unit but it wouldn't work. We then turned off the main for a few minutes and turned it back on and it still automatically started running. Please help as we have had to turn on of the main switches off but that has also affected half the hours sockets. Thanks and much appreciated.

Check for power at the plug in, if it's got power take it back under warranty.

SOURCE: MY AKAI LCT3201AD TURNS OFF BY ITSELF

If you are electronically inclined, replace the three 1000uf 16v electrolytic capacitors in the power supply board located above the power switch. They are likely bulging out at the top and failed. They are the three in a row at the top - center of the board, located between the two black heat sinks. Make sure you get caps rated for 105c degrees! I recommend replacing them with 1000uf 25v caps. 35v caps will work but might be a tight fit as they are larger diameter.

Should cost you about $8 for the parts shipped. You can get them from partsexpress or digikey or any good local electronics store. Your local radio shack may have them but they won'y be 105c and thus may not last long.

Not handy, ask around, there is usually some electronic tweaker guy around that will install them for a few bucks.

This has solved the turns on / then off problem every time in the 3 I've done.

SOURCE: LG Split unit turns itself off after a couple of seconds of opera

Check your remote control using your camera or cellphone camera as your eyes. Point the remote control transmitter to your camera and "on", light should emit in your remote control transmitter (means good remote). Reset the unit by disconnecting the power supply for 10 sec. then "on" again and start the unit. If it wont work you need a qualified tech. to solve the problem.Some of your safety device might be defective.

Panasonic cs-w9dk air condition problem


If this is an old unit then you must check the filters, the voltage to the compressor units. If the motor capasitor is weak then the compressor might shut off due to strain and high current drain.
Try and clean , blow air jet into the condenser and also clean or replace the filter and the evaporator. In short the unit needs a check on the gas pumping, if there is shortage of gas and also if there is fault in the power.

Coils freeze up


The first thing to do is see if the indoor (evaporator-air handler) fan and compressor are both running at the same time, then turn the unit off and let all the ice melt.
If the compressor is running and the evaporator fan isn't, you've already found the main cause of your air conditioning freezing problem.
The indoor coil will freeze up if the compressor runs without the evaporator fan running.
Check to see if ice has built up enough to stop the fan.
If it has, (and it's possible with wall mounted ductless mini split units and some window units), the fan may run normally once the ice melts, and the cause of your air conditioning freezing problem could be something else.
If you are the equipment owner trying to take care of this air conditioning freezing problem yourself, and you get to the point that you have to call in a technician, it could save him time, (which saves you money) if you have already verified whether the evaporator fan was or wasn't running with the compressor, and if ice had built up enough to stop the fan.
Once the ice has melted, check the fan or blower blades, and see if they're clean and not obstructed by something like a plastic bag, other debris, or mould growth.
Remove any obstructions, and if necessary, remove the blower and clean it.
Before tearing into the rest of the unit, check the thermostat and make sure it's working right.
Do the cool contacts open when the t-stat is turned up to a higher temp than the room temp?
If not, the thermostat has failed, and never turns the unit off, which can definitely cause an air conditioning freezing problem.
Do the fan contacts open and close when the thermostat setting is turned higher and lower than the room temperature?
If the fan contacts never close but the cool contacts do, the thermostat has failed and caused your air conditioning freezing problem.
If the fan contacts close, but the fan doesn't run, check the fan relay in the air handler.
If the fan relay is not getting control voltage, the circuit is open between the thermostat and the fan relay.
Look for a loose connection, wrong connection, dis-connection, or broken wire.
If it gets control voltage but doesn't energize, it has failed, and must be replaced.
If it energizes but the fan doesn't run, check for line voltage on the load side of the relay.
If there is line voltage on the load side of the relay and the fan doesn't run, you'll have to troubleshoot the load side circuit and the fan motor as detailed further on.
If the thermostat checks out ok, set the thermostat to "fan on" and make sure the blower runs in the correct direction and at the proper RPM, that it is installed in the housing correctly, and is the right size.
If the blower is installed backwards or is running in reverse, the coil can freeze up. (Although I have seen several units that didn't freeze up with reversed blowers.)
You will need to turn the blower around, reverse the rotation of the motor if it is a reversible rotation motor, or install a motor with the correct rotation.
A blower that runs too slow can cause an air conditioning freezing problem.
You'll need to install a motor that runs at the correct speed.
A blower that is too small, or that is installed in the housing incorrectly, can cause an air conditioning freezing problem.
You will need to install the correct size blower, and be sure it is installed correctly in the housing.
This means centered, with volutes installed, and the curve of the vanes matching the outlet of the housing.
If the blower motor is the wrong size, if the bearings are failing, or if it has an open start winding or a failed run capacitor, it could be overheating and stopping intermittently.
A motor that is overheating and stopping intermittently can cause an air conditioning freezing problem.
To check out the evaporator fan motor:
Check the resistance readings of the motor windings.
If you get a readable resistance between all three windings, the motor windings should be ok.
Turn the shaft. If it turns free and easy, the bearings should be ok.
If the shaft is hard to turn, lube the bearings with 20 SAE electric motor oil if there are lube ports.
If that frees the shaft, it should run ok for a while, but the bearings or bushings may be deteriorated to the point that they'll sieze again soon.
If the shaft doesn't free up, replace the motor.
If the shaft turns freely, check the capacitor.
The best way to check the capacitor is to replace it with a new one of the correct rating.
If the motor runs, close the air handler panels, and take an amp draw on the motor.
If it's normal it should run OK, and if the motor was the problem, your air conditioning freezing problem should stop.
Ok, if you've verified that the controls and fan are good, take a break for a diet soda, and then we'll see if the evaporator coil or ducting are the cause of your air conditioning freezing problem.
Take a look at the evaporator coil.
Is it clean? Can you see your flashlight shining through from the other side?
If the coil's dirty, you'll have to do some air conditioning coil cleaning.
If your air conditioner is a window type, our page about how to clean window air conditioners has some pointers you might find useful.
A dirty evaporator coil is a common cause of air conditioning freezing,
And it's one of the problems that can be prevented with regularly scheduled air conditioning maintenance.
If the coil is clean, check the ducting to make sure nothing is blocking air flow.
Blocked ducting will stop air flow through the evaporator coil, and this will cause the coil to freeze up.
If your coil is clean and the ducting is clear, let's run the unit and check the operating pressures and temperatures.
If your discharge and suction pressures are low, with a low compressor amp draw, low subcooling, high superheat, and low temperature splits accross your evaporator and condenser coils, you probably have a leak.
Shut the unit down, find the leak and repair it.
Once the leak is found and/or repaired and you're ready to run the unit, our Charging Air Conditioning Systems page offers some tips that you might find helpful.
If you are totally unable to locate the leak with a bubble solution or electronic detector, you'll have to charge in refrigerant to correct pressures, temperatures, and superheat and subcooling values, and it would be a good idea to add some air conditioning leak detector dye so the leak can be found later on.
You have to use some common sense about leaks.
If the leak is so small that you can't find oil or any other sign; unless the customer agrees to pay you for all the time you spend, it's more cost effective to charge in the small amount of refrigerant it will take to get the unit running correctly, finish the service call, and be on your way.
I can't imagine that there's a service technician out there who hasn't run into the same problem many times.
Use some common sense, be up front with your customer, and if you've done your best not only to find the leak, but to get the unit running right and save your customer unnecessary expense, consider it a job well done.
If your suction pressure is low enough to cause the evaporator to freeze up, but you have high subooling and high superheat, either your metering device is restricted or the wrong size, your drier is restricted, or your liquid line is restricted.
Evaluate all of the system's operating characteristics to isolate the restriction.

I cannot turn on my surround sound on my Philips MCD700 Stereo using the remote, any ideas???????


So are you saying the remote doesn't work or that the unit itself doesn't work? Walk over to it and press the power button.

Read this procedure to possibly fix the remote:
http://remotes.com/remotes/servlet/rs?a=Display&contents=help_deadremote&uuid=A12963989782821
They also sell replacement remotes.

Zoom in on the picture of the original remote provided on the site (or look at your own) and get the actual remote model number.

or check eBay: search for "(model of the device or the remote) remotes", check the 'include description' box. Usually cheaper than the vendors.

Cannot reset remote for braemar Ecostar Ducted heatin. Need to reset time and day. Would like to reset programmes also however when i hit the set button as per instructions in little book provided the...


The Braemar heater I have is wired directly to the control unit. The only way to reset the time is to turn of the heater for 5 minutes - the remote display should clear, and turn it back on (takes a minute for remote to come back on) the time will be flashing - use the Up and Down arrows to set the time, and SET button to set the day of week.
