Starting the AC compressor against high pressure, whether due to an overcharge condition or a restricted component can . That will clear the error code. They keep food fresh over a long period and in varying temperature conditions. Use a multimeter to check the condenser fan motor for continuity. It is ideal to set it to 5. That sounds like a burned up compressor that is also shorted. Any thoughts? Unplug the fridge and pull it away from the wall. Return the ice bucket to its position and leave the ice maker for 24 hours. thank u somuch for the information i love your blog is educating,i love tobe receving mail on your update espercial on Ac/fridge, tank you ones again. The lower the resistance, the higher the current flow. Then, allow the refrigerator up to 24 hours to normalize the new temperature setting. Otherwise, it is the water pressure. Touch the meter leads to the corresponding leads on the start capacitor, red to positive and black to negative. Unlike the traditional compressor that stops running when the compartment becomes cold, then kick-starts again, the linear compressor works differently. If it is hotter than usual, it is a sign something may be wrong with the compressor. And you already know what the consequence is. A) A: common B: start C: run B) Cannot identify terminals: winding grounded Consequently, the other components will fail to function appropriately and the refrigerator stops cooling. However, the NFPA and IEEE have recommended a ground resistance value of 5.0 ohms or less. Otherwise, there is no route for electric current to flow from the probe to probe. Post photos, respond to polls and access other special features. Not all resistive loads behave in this way, though.
