The thing you call a transformer may be a relay. That's the real control of the compressor. It has a moving part, and it makes a good click when it moves. It is controlled by the thermostat. You should have 220 in, 220 out. There is a delay timer in there somewhere, it's a square thing, probably says delay timer on it. Those two items are likely to fail. AC repair is a good field, you could apprentice yourself to a service man and pick up a lot

The distance of the cord is a big deal, 10AWG Cord would be best for this situation. If you have a 50ft cord, make sure that the cord is not wound up on top itself as this can cause a drop in voltage and a spike in amperage. Is the compressor trying to come on at all? If not, then you may have a problem with the selector switch or the thermostat. If the compressor is humming for a few seconds and then stopping and then trying to come on again, it could be a problem with voltage loss. Anything below 98.5 plus or minus 10% is too low the for the compressor to kick on.

Subzero refrigerator not getting cold


if both the freezer and fridge are getting warm you either have a bad condenser fan motor or the coil has to be cleaned.this is how i do it for my customers,i have a shop vac a small one it's called a stinger,with a brush attachment i clean the right side of the coil vacing it with the brush,then i shut down the machine,put a towel across the opening but first remove the white cover like you did and then set the vac to blow by sticking the hose on the other side of the vac and blow through the coil,the towel blocks all the dust so it doesn't fly into the kitchen,then vac up anything that got loose,do it a few more times and then go on the other side where the fan is and blow it through that way,the coil gets filled with dust and just vacumming the outside just ain't good enoughmalso if there's grease on the coil you can spray it down with grease lightning or any grease remover you like,then hit it with water from another spray bottle and blow it through again,you have to do this at least once a year to keep it clean,then get a flash light or drop light,stick it in on the right hand side and look through the fan opening,if you can see the light shining through the coil is clean,turn it back on and make sure the fan is blowing strong and you should be fine.hope this helps

Unless we set the thermostat very high, like 80 degrees, the heater will blow cold air. When the heat does blow, it will eventually stop blowing heat and the fan will continue to blow cold air.


Check and make sure the filter is clean. This sounds like a restriction in the system. If the unit has central cooling make sure ther indoor evaporator coil is clean at the furance.The unit may be cycling the burners on and off at the high heat limit , fan/limit control. You can also eliminate the thermostst from the furance. Turn power off at the furnace and disconnect the wiring from the thermostat. Jumper the red and white wire together. Turn the furnace back on. The furance should run in the heating mode. Try this and see if the problem is still there.

Hi, it sounds as though you had a problem with the disconnect box which is the only thing located on the exterior of the unit. You have to remove the cover to get to the wiring and fuses. Probably had bad fuses. In this case, the unit is up and running, so this wouldn't be the problem.It might be several things, like you may have a freon leak and lost some, or the condenser coil on the outdoor unit could be very dirty causing this not to cool. Try cutting off the power and taking your garden hose and washing the outdoor wrap around coil real good to remove any dirt build up. Careful not to use to much water pressure as you will flatten the aluminum fins. This might be your problem causing high head pressures. Do this and see if it does the trick.Make sure the fan is running and you can hear the compressor running also inside the unit. If its not running, you will have no cooling. Clean the coil and we can go from there. Get back to me and let me know the outcome, and we can go from there.
Sincerely,

M refrigerator isn't cooling the evaporator coil was full of dust it looked like it had a sweater over it but it still isn't cooling after I cleaned it what should I do


Don't you mean your CONDENSER (the black tubes found at the back of your unit or below it ? Those are the ones that dissipate the heat - if they are at the bottom, there is usually a fan blowing air on it, if applicable, check to see if it is spinning, when the compressor is on.

The EVAP coils are the ones you find when you remove the freezer's back panel, you will see a fan there, blowing the cool air from the evap coils.

If the evap coils in your freezer are over frost it will cause cooling problems, in which case your defrost system is not functioning and you will need to change the control board and have the defrost components checked to make sure everthing else is working.

Why isn't my Sunbeam Window A/C blowing hard on high?


If the air doesn't seem cool enough it is necessary to use a thermometer to check the difference in temperature between the air going into the unit and the air being blown into the room. Ideally, the temperature difference should be more than 15 degrees. For example, if the temperature going into the air conditioner is 80 degrees, the temperature coming out of the unit should be at least 65 degrees or less. If the difference is 15 degrees or more there is probably no cause for concern. If the temperature difference is less than 15 degrees you should check the following:

  • Air damper

Check to make sure the air damper is closed. If it's open, it will bring in outside air and reduce the efficiency of the unit.

  • Back cover

During the winter season many people cover their air conditioners to protect the unit from the weather. In the spring or summer they will sometimes forget to remove the cover. If your unit has a cover on the outside portion of the air conditioner remove the cover first.

  • Condensing coils

The condensing coils will always be on the "warm" side of the air conditioner. That is, on the side that faces outside of the room to be cooled. Air is drawn into the back of the air conditioner on the sides through vent slots and is blown directly out through the condenser coils. If the coils get clogged with lint, dust and dirt the cooling system cannot provide the cooling necessary. To clean the coils it will be necessary to remove the entire cover of the air conditioner or pull it out of the wall to gain access to the coils. They can be cleaned by blowing compressed air at them or by using a soft bristle brush to wipe the dirt off. It is important to also clean any dirt or lint build-up in the bottom of the air conditioner so the condensate water will be picked up by the condensing fan slinger properly.

How to Clean 1984 TRANE Cooling VENTS inside house No Manuals


The Outdoor unit will be easy 1st diconeect power at panel, or disconnect box near unit. Remove top of unit, be careful not to damage fan blades. Spray coils (fins) with a light degreaser let is soak for 5 mins. wash out coils from inside the unit out. Spray straight on so you push the dirt out the other side.

Re assemble and start up.

Indoor coil will be accessed by removing front cover and you may have another cover to expose the inside of the coil fins. That is where you need to clean. Spray degreaser on coils and rinse off. If its gunked up then use a wire brush 1st. Carefull not to bend the fins over.

Check the drain pan at bottom of the coil to be sure it's not full of stuff. Blow out if needed.

You should be clean and ready for the season

Durotherm Model 57915.331 - not cooling properly


Yes, you should remove the upper cover and check the back side of the condenser as Duo-Therms pull air in from the sides and blow it through the coils from inside the shroud. This usually will cause the compressor to shut down, but only after running for awhile. When you notice that the unit is not cooling as well, or not at all, got up on the roof and remove the shroud, check to see if the compressor is actually running. If the compressor is shut off, the problem lies elsewhere in the system. Check to see if the compressor is cycling on and off or if once it is off it stays off.
If you have a wall thermostat control, check for 12VDC power at the yellow wire when the compressor is off. If power is present, then remove the control box from inside the inner shroud of the unit and check for power at the yellow wire in the there. If it is still present, check for 120VAC power at the compressor relay (black wire with Purple or Blue wire). If the purple or blue wire have 120VAC power, then the problem is upstairs either with start capacitor or the thermal overload (located on top of Compressor). If there is no power at the purple or blue wire, try unplugging the freeze control and jumper the connection on the board (blue connection, white wires) with a small piece of wire, if the compressor comes on and runs, then you have a bad freeze control. If not, then you have a bad control board.
If you have manual controls on the ceiling unit, you could have a bad thermostat. Unplug power from the unit and remove the two wires on the back of the thermostat. With an ohmmeter, check for continuity between the two terminals, if there is, turn the knob and watch the meter. You should not lose connection until the temperature you set is above the temp. inside the unit. If this is ok, then you need to check the selector switch. Also check the components in the upper unit as described in the above paragraph.

Hope this helps,

Jeff

Not blowing upstairs not coolin


Hi,
The compressor is a football-sized case with no apparent moving parts. It is located inside the air conditioner at the center. Is it humming or making any kind of continuous noise or causing the lights to dim? If it is making a continuous noise, and your air conditioner is still not cooling at all, there may be a serious problem with one or more of these areas:

  • Compressor


  • Condenser


  • Evaporator


These items are not user serviceable. You will need to contact a qualified appliance repair technician to repair these components.

If the compressor is not running but you do have power to the air conditioner there may be a problem in one or more of these areas:

  • Compressor


  • Overload and/or relay


  • Thermostat (Open thermostat)


  • Burnt wiring


  • Bad selector switch


  • Capacitor
