If the heating element tests OK, you should next check all the electrical wiring from the dryer timer assembly, thermostats, and drive motor. Electrical wiring in a dryer becomes brittle and burned because of the excessive heat. To locate defects in the wiring, use a volt/ohmmeter to make continuity checks on wires that you suspect are faulty.
The problem of no heat in the gas dryer is much the same as the electric dryer, except that instead of checking for a possible defective heating element, you must check the gas ignition circuit. A sure and simple test is check voltage to the gas burner wiring harness. Read the rest of this entry »

Using hand tools, remove screws and discard the defective water supply valve. When installing a water supply valve on the water heater, install only on the cold-water side of the water heater. Read the rest of this entry »
The term ‘harness‘ is used for all of the wires that connect the various components within an appliance. In large appliances they are usually bound or fastened ‘together in bunches to keep the wiring neat and safely anchored. Smaller appliances, however, may sacrifice neatness for safety and route the wiring to avoid contact with heat or sharp edges. The correct positioning of wiring also contributes to the double insulation of an appliance, so no alterations whatsoever should be made to the routing or position of the wiring in double insulated appliances.
When you first take a look at it, the harness may seem like a jumble of wires thrown together, but if you take the time to inspect it, you will find that each wire is colour-coded or numbered either on the wire itself or on the connector at each end. This allows the engineer to follow the wire through the appliance easily. With a little practice, any wiring or coding can be easily followed. Read the rest of this entry »
