If the fan blade is hard to turn then you probably need a new motor. Use 80% of the R-12 charge. It is just poor construction. Please see Term-Lok compressor terminal repair kit above on this page. The Air conditioner outdoor unit will not come on.

I hope this has helped you to trouble-shoot and repair your air conditioner! Most contactors are on or near the condenser coils. If you have gauges the low side at idle on a hot day will be about 40-50psi. Keep slowly adding the freon until the can gets empty. Read the instructions on how to connect the new fitting on the low pressure side. The Super-Boost could save you from having to purchase a new air conditioning compressor or system! Check your wiring diagram for the type of air conditioning or heat pump contactor you need. The best way to tell is by hand.

Contactor Replacement

What is bad to one person is not bad to another. If the compressor is hot then the compressor could be out on thermal over-load. I have never been shocked by a capacitor knock on wood and rarely see them discharge, but it is a good idea to discharge them before working around them. It is really cool and rewarding when you see that bright yellow leak shining back at you!

Long Air conditioning run times. Either the outdoor fan does not run, the compressor does not run, or both the fan and the compressor do not run. Lennox Pros: You can never have enough contactors. If you have children living in your home, renters, or other people who do not understand that you should wait 3 to 5 minutes before cycling and air conditioner off and on. This lid will probably be heavy as it's attached to the fan assembly. This relay turns your condenser on and off when your indoor thermostat determines that you need more cool air inside. Sometimes it can take 2 or 3 hours for a compressor to cool down.

Click on the Contactor Link to learn what type of contactor you need. Sincerely, Steve Arnold, President, Arnold's Service Company, Inc. On several service calls I have seen all that it takes is a flip of this little lever on the thermostat. It continues to run no matter what you do. I have seen them continue to operate for another two years.

Blue wire on the left side and a brown wire on the right side. Since it's already disconnected, it should be easy to fish through now. Thanks for reading my frustrations with finding refrigerant leaks. Please remember to turn off all power when working on air conditioning equipment. On central units the thermostat on the wall sends 24 volts 24 volts comes from a transformer in the blower housing to relays and contactors that switch the power on and off to the compressor and motors. Turn the furnace off or thermostat off so no low voltage is going through the low voltage wiring. Over time the spot where the wire and the connector meet look for corrosion, heat damage, rust, ect.

Slow or dragging blower motor might need a new capacitor. Here is the one for this unit. In the old days you could just depress the valve to let what is left of the R-12 out. Looking For The R-134 Refrigerant 134a Temperature-Pressure Table Temperature F 134a Psig -60. R-134 is less per lb. You just saved big bucks and extended the life of you air conditioning system! I have seen 1 or 2 inches of ice form on the line set and outdoor unit compressor. The second low voltage short failure that week was traced to improper wiring.

A backfeed or improper common through the control system can give false readings. If not, make sure there is the correct control voltage at the terminals. It is a breaker type you may have the pull out type. When all of the control wiring is removed from the diagnostic, then the ac system can be tested by jumping the controls directly at the control board. Dirt or insects I see ants many times can get in between the contact points while the contactor is off, and cause the air conditioner not to come on at all. The is not always true but is true a majority of the time.

A lot of air conditioning technicians cannot read schematics very well if at all. Sometimes the compressor terminal cover can be a bear to take off. If you have electrical storms where the power is going off and on. The gas burners will not light, the outdoor air conditioning unit will not come on. But if you look at the one we have here. Lets look at a few examples.

I hope you can get your air conditioner up and running again soon! Feel the tubing at the compressor by hand it should feel very cold, like an ice cold soda out of the refrigerator. You may only have two or one if you are performing this repair on a package system. Below I explain the job of a transformer. On the first can turn it upside down. The technician began by reading 24V at the contactor in the condenser, but the contactor would not engage again. You might need to purchase a contactor that we have listed above on this page.
