Johns Creek Appliance Repair Pros Rules

Go to the Johns Creek Appliance Repair Pros that is supposed to do the work, and verify that it has the correct voltage to it. For example, if the heater on the dryer is not heating, and you have already eliminated rule number one, and rule number two, verify that the heater has voltage to it. If the heater on the dryer has voltage to it and it is not heating, it’s defective. It’s as simple as going to a lamp and checking the light bulb because there is no light. It would not make sense to start disassembling the switch on a lamp, because there is no light. The component that does the work is the light bulb. On appliances, the components that do the most work are the components that fail the most.If you are unsure of your ability and do not want to check for voltage at the heater, you can check the element for resistance. Before you attempt this next procedure, verify that the appliance is disconnected from the electrical supply. You can isolate the heater by removing one of the heavy wires to the terminals on the heater, use an ohmmeter, and check for the resistance of the element.


Backup your diagnosis. Backing up your diagnosis will help prevent you from buying an appliance part, installing it, and then attempting to return it, because that was not the problem. As a rule, appliance parts dealers do not allow the return of parts that have been installed. This is because electrical parts that are installed on appliances can be damaged, and that damage isn’t always obvious.

So what do we mean by backing up your diagnosis? It means to use whatever is necessary to confirm that the part you are calling defective is actually defective. For example, if you find that an operating thermostat on a dryer has an open set of contacts, you can use a jumper wire across the contacts to confirm that the heater will heat. Never use a backup device such as a jumper wire to operate an appliance for any length of time. This is simply unsafe. If you use a jumper wire, to jump across a set of contacts, whether that be a selector switch, door switch, lid switch, or timer contacts, you can use your ohmmeter to check for resistance. To do that, you would put your ohmmeter on the line cord coming from the appliance to check for resistance. If you made a mistake and accidentally jumped out the wrong set of contacts on a timer, plugging it in will damage the timer and possibly other components. An appliance is a device that does work and it must have resistance to electrical current flow. The resistance of an electrical wire is zero. Therefore, the resistance of an appliance has to be something other than zero. Zero resistance on an appliance cord indicates a dead short.
