The four oxygen atoms in a phosphate i â¦ on therefore have a total electric charge of -8, and the phosphorus atom must have an oxidation number of +5 to result in a net charge of -3 for the whole ion.
Remove the front lower panel on the refrigerator with a screwdriver and set the panel aside. Disconnect the wire connectors from the capacitor and terminal that are connected to the compressor, using your hand. Lift the compressor out of the bin and set it aside.
If neither runs and the compressor is hot, unplug the fridge and point a fan or a hair dryer set to âno heatâ at the compressor. Wait for the compressor to cool and try again. If the compressor runs but the fan doesnât, the fan is bad. Unplug the refrigerator and replace the fan (Photos 5 and 6).
