Air Conditioner Problem
I know this is Technicly a non-Electronic type appliance, but perhaps
someone can provide insight on this Problem with a Window AC unit.. This is an older Sears Coldspot, probably 5000 BTU. When 1st put on, it will blow cool Air ok, but after a While you can hear the cooling grille Disconnect Electrically, probably from the Sensor mounted to it , which goes to the Thermostat Dial on the Front panel. Then, Depending on I think how much Water has accumulated inside the Unit, it may or may not re-engage the Cooling Grille. It seems on hotter days it tries to turn on the Cooling grille but you can tell its drawing ALOT of Wall Current (the lights dim) and you can hear a breaker in the AC Pop....the Fan Continues to blow whatever cool air is remaining ok....but after a short time it will try to re-engage the Cooling grille. Sometimes it will kick in ok , sometimes you just hear the breaker pop out again and again after repeated attempts. Last night I re-positioned the wire type Sensor mounted on the cooling grille, and It blew cool Air Ok, with no problems. I just moved the wire away from being embedded in the grille so that just the Tip on the Block is touching the Grille. This morning, it seems we have alot of Condensation & Water dripping inside, and the problem came back. I tilted the Unit to better drain the water, and it seemed to help. Am I on the Right path as far as the Water Build up goes? |

Air Conditioner Problem
It is very normal to have water build-up. The machine is extracting
moisture from the air passing through the evaporator. The machine must be mounted at an angle to allow the water to spill back to the outside section where the condenser is. There should be some drain holes for the water. Many machines also use this water as part of the system for cooling the condenser section. There are supposed to be overflow drain holes, or some way for the excess water to drain off. You should consult the technical manual for your machine, or enquire to their service department about where the thermostat sensor should be positioned on your model. This should be correct in order for the machine to perform properly. At least once a year, or every two years, a window unit should be properly checked and properly cleaned with high pressure steam equipment. Then it should be tested for performance and reliability, and any worn parts changed. This will keep the machine in top running condition, and work efficiently so there is no wasted use of power for its operation. I realize that air conditioners are not very expensive these days, but proper maintenance will effectively make it more efficient. -- Greetings, Jerry Greenberg GLG Technologies GLG ============================================== WebPage http://www.zoom-one.com Electronics http://www.zoom-one.com/electron.htm Instruments http://www.zoom-one.com/glgtech.htm ============================================== "techforce" wrote in message t...

This should be correct in order for the machine to perform properly. Come on Jerry, this is a window A/C. At most it has a manual to tell the user how to turn it on and off. The model is probably 20 years old and the chance of finding exact service info is nill. The location of the sensor is important, but the problem he is describing sounds like the compressor is hard-start once it shuts off. If the compressor shuts off and then immediately tries to restart, it will fail and pop the overload protector as described. This is normal behavior but shouldn't happen unless someone moves the thermostat to a colder setting just after the compressor shuts off. After a couple of minutes once the pressure equalizes, it should restart fine though. At least once a year, or every two years, a window unit should be properly checked and properly cleaned with high pressure steam equipment. Then it should be tested for performance and reliability, and any worn parts changed. This will keep the machine in top running condition, and work efficiently so there is no wasted use of power for its operation. Wishful thinking and while this does affect the efficiency, the basic mechanical operation should be reliable without frequency maintenance. We all make recommendations that are unrealistic. --- sam | Sci.Electronics.Repair FAQ Home Page: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Site Info: http://www.repairfaq.org/REPAIR/F_mirror.html Important: The email address in this message header may no longer work.
