Alarm on

hector...this sounds like icing up! First thing is to defrost this unit. The ice is preventing air flow over the coils. Shut down and get warm air to the coils. Then, let everything dry. If you leave off and open for 2 days, this will do it. Causes: humid conditions, 'window shopping' or bad gaskets. If the gasket surfaces are dirty, clean them. Test any questionable areas by taking a 2-3 wide strip of paper and close the door on it. If the paper pulls easily, the gasket is bad.

Now, clean out the condenser coils. They are located in the back or under the unit and are always painted black. Then, have a look at the compressor. It is that big black thing in the bottom with pipes sticking out of it. Look at the larger pipe. When you start the unit, it should frost and then either dry off or condense water after about 5 minutes. If it stays frosty or is not cold, you need gas. If the unit passes all these tests, you may have a defrost timer issue. Let me know.
