SOURCE: ATWOOD MOBILE FURNACE RUNS WHEN IT WANTS/

Check your furnace for power. will be 4 wires. power ground and 2 thermostat wires. Check for power at the time delay relay, if you have power there check for power going in the fan motor, if power in motor wire, motor is bad. If no power in motor wire and power going to circuit board take the 2 thermostat wire apart and wrap the 2 together comimg from the thermostat. Fan will stat in about 30 seconds. If it does you need a control kit in the ac. But sounds to me like you have a furnace problem.

Hi, you can use this troublle shooting tips..

First, you want to make sure that you have power at the plug that you are using for your air conditioner. You can test it with a voltage meter or simply plug something else into the same outlet (if the receptacle is 220V, you will need to measure it with a voltage meter). If it works, you know you have power to the air conditioner. If it doesn't work, you'll need to check your fuse panel for any blown fuses or your circuit breaker box for any tripped circuit breakers.

Air Conditioner Control

If you have power, it could be one of several problems that are keeping it from running. Many times an air conditioner can't start the compressor if the amperage or voltage is too low. This can happen, especially if you run the unit from an extension cord or have something else that draws a lot of power on the same line. The compressor initially takes a lot of power to start.

Air Conditioner Switch

If you hear any odd noises coming from the unit, it could be the compressor trying to start, but unable to do so. Another part that causes odd noises is the overload/relay. This causes a click-buzz-click sound near the compressor. This is the overload/relay working, and it protects the compressor from damage by cutting power to it if there's a problem. If you hear this, the compressor has power, and it means something is wrong with the compressor. If the compressor is the cause of the problem, you'll need to contact a professional appliance repair person.


Air Conditioner Thermostat

Also, any of the control components could be the cause of your problem. These include the control board, the selector switch, and thermostat. The control board controls the overall operation of an air conditioner, and if it is bad, it may prevent the unit from operating. The selector switch is used to adjust the settings that you want on your air conditioner. The thermostat controls the temperature. In addition, the wiring between any of these components could be to blame.

Sometimes the plug for the unit gets burned on the end that goes into the outlet, or the outlet itself gets scorched. This will reduce the contact points and may not allow any or enough power through to operate the unit. If this is the case, you need to replace the plug and outlet as it is also a fire hazard. You may want to call a professional electrician for this job.

Air conditioning is an important part of climate control in many homes, offices and public spaces, thanks to its ability to regulate hot temperatures during the summer. The Haier air conditioner is designed to fit inside a window slot and draw warm air from outside the building as opposed to standalone air conditioners that require a special intake pipe to be installed. Troubleshooting your Haier will aim to solve the most common problems.



Verify the air conditioner is plugged in to a working electrical outlet. Switch the outlet on if your home is fitted with power switches for its electrical plugs. Confirm the outlet is working by plugging in another appliance.
2

Press the "Power" button on the air conditioner's control panel and turn the fan dial up from "Min." Once the AC is plugged in, it still needs to be switched on and set up. An extremely low fan speed may give the impression the appliance is not working.
3

Use the air conditioner only when the outside temperature is above 65 degrees Fahrenheit. The compressor inside the appliance does not work until the outside temperature is warm enough.
4

Pull down the grille on the front of the air conditioner to reveal the air filter. Lift the filter slightly upward and remove it from the appliance before placing it in a sink of warm, soapy water. Clean off any dust or lint that may be stuck to the filter and allow it to dry. Put the filter back into the air conditioner and close the grille. Dirty air filters can restrict the air conditioner from working properly.
5

Ensure all windows and doors leading to the room you are trying to cool are closed and all sources of heat, like ovens and clothes dryers, are switched off. Certain environmental factors can limit the efficacy of the air conditioning. Ensure nothing is blocking the flow of air out of the front grille.

Furnace will not run when hooked up to electricity


Go to your thermostat and access the fan mode. Change the fan mode to Automatic, AU. This will stop the AC fan from blowing when the furnace is turned on. If the fan mode is on Hi or Lo and the furnace is turned on it will turn on the AC blower. Bad design...

Multiple clicking sounds coming from AC unit before AC unit turns on or before furnace turns on.


the is a 24v wire that feeds from your thermostat to your unit, inside there is a contactor that engages, this makes a click sound as it really is a basic mechanical part the makes metal touch metal to allow current to flow through the system, perfectly normal, your hearing the low voltage engage the highvoltage at the contactor.

Heat and Air run at the same time in my rv


yes, replace your stat but also make sure your wire going to y on the stat has not shorted with the wire going to the w on your t-stat. To check to make sure remove the t-stat and short the wire going to r to the y wire and the wire going to the g terminal if it has that. if cooling works with no heat it's more than likely in the stat, if heat comes on then you may have other wiring, circuit board issues

My thermostat says -AC WHAT DOES THAT MEANB


Turn your fan from auto to on at thermostat, fan should come on. If
you still get the (AC) and fan does not come on, change the batteries at the thermostat if they have them..

To see if thermostat is bad, do this.
1) Turn power off to Furnace/AirHandler.
2) Remve Bowler Door and find where thermostat wires connect to control board. Remove wires and write down which terminal they go
to.

3)Take a wire and hook-up between R and Y. Put door back on, turn power on. Fan should come on and AC should come on.

Hi Proper way on wiring furnace.


I can give you a start, For heat only, R terminal on furnace to Red wire to R or RH terminal on thermostat. W terminal to White wire to W terminal on thermostat. G terminal to Green wire to G terminal on thermostat. This will get you heat but not air conditioning.

If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.

Furnace blower motor


I would check the "G" wire at the Thermostat and make sure that it has a solid connection. The other end screws on to a terminal in the furnace. Check this connection as well. This green(G) wire is what activates the 120v relay on the circuit board. You can test this by turning the thermostat to the off position and then jumping the 24v R terminal with the 24v G terminal at the furnace. if the fan comes on then the problem is in the thermostat wire or the thermostat itself.
