If the timer contact terminals show continuity and you find no voltage at the temperature selector switch, then you must make a continuity check for burned or broken wires from the timer assembly to the temperature selector switch. With the volt/ohmmeter dial set on the RX-1 scale, disconnect one wire from the terminal of the selector switch and attach a probe. Touch the remaining probe to the other end of same wire. If the wire you are checking is good, continuity (0 ohms) will be measured on the volt/ohmmeter. Read the rest of this entry »
Unplug the power cord or gas supply before servicing the clothes dryer. Move clothes dryer out from the wall. Exercise care when moving the dryer from its original position because the dryer legs can easily tear holes in your floor.
Remove screws to dryer top. Lift the top of the dryer by inserting a flat-blade screwdriver between the cabinet and the top of the dryer. Remove the screws that secure door switch to dryer front panel and discard the door switch. Read the rest of this entry »
There are three types of failures that are associated with the Fridge start capacitor. These failures are a defective capacitor. an open filament capacitor, and a grounded capacitor. You can check each of the above failures with the volt/ohmmeter. First, unplug the Fridge power cord. Using hand tools, remove the screws that secure the Fridge back and remove the starting capacitor from the compressor starting package. Look for traces of oil on or around the capacitor. If oil is present, the capacitor is defective.
CAUTION: A charged capacitor is extremely dangerous. A capacitor that has been removed from the compressor starting package will hold a charge indefinitely, even when not in use. If you touch the terminals of a charged capacitor, the built-up voltage could give a high-voltage shock that could be fatal. A flat-blade screwdriver across the terminals should be used to discharge a capacitor. Read the rest of this entry »
These operate at elv (extra low voltages) between 3 and 12 V. The single bell, buzzer and many models of chimes are powered by dry batteries but the more powerful chimes and intricate bell systems have to operate from mains transformers. Usually a transformer is preferable for any bell or chimes. Where an illuminated bell push is used a mains transformer is essential as the lamp of the push would exhaust a battery in a day or so.

Unplug refrigerator power cord. Using hand tools, remove the icemaker from the freezer section of the refrigerator. Remove the front cover from the icemaker. Remove the front component plate that is secured to the ice maker support housing. Remove the screws that secure the cycling thermostat to the icemaker support.
Remove electrical wires from the terminals on the support housing, and carefully remove the thermostat. Read the rest of this entry »
Specific symptoms include: Little or no water enters the dishwasher tub cavity. To find the cause, first check to be sure the water supply is ON.
To avoid incorrect readings when using the volt/ohmmeter, always “zero” the ohmmeter before making any continuity checks on dishwasher components. See operating instructions that came with your volt/ohmmeter.
When making continuity checks with the volt/ohmmeter, always turn the electricity OFF at the circuit breaker panel. Live voltage checks will damage the meter movement. Read the rest of this entry »
