Dryer Venting & Installation Guidelines
Check for Brands
Most repairs to dryers(depend on brand) require that you remove the top and front (not the back or sides) to access the parts. |

Dryer takes too long / usually caused Checking air flow and venting hose
While your dryer is still running, and before you disconnect its power supply, place your hand over the exterior vent while it is running. You should be able to feel a strong air flow. If the air flow is weakened at all, check the following areas: Airflow restriction General Trips: Airflow restriction is the problem causing long drying times. The ducting could be to long causing lint to build-up inside of ducting. Lint than will collect moisture causing a back pressure build-up, thus clothing will stay wet. Fabric-sheet film build-up on the lint filter what causes dryer units to catch fire and potentially burn the house down." The best way to avoid these problems, is to take that filter out and wash it with hot soapy water and an old toothbrush (or other brush) at least every six months. The duct can caked with lint. And once it is caked with lint can soak up the moisture become wet. This because all that water that came out of the wet laundry had to go somewhere, if it doesn't making it all the way outside. Staying inside the dryer, clothing or ducting, it can become so wet that water will dripping out of the duct at the joints, getting into the wood(wood-rot) and the back of the drywall, where it will start to grow black mold. All of this damage can add up to $10,00o dollars of damage. Worse a fire! |
When replacing ducting DO NOT USE VINYL PLASTIC DUCTING - FIRE HAZARD

Learn to use Multimeters
|
*Continuity test is the checking of an electric circuit to see if current flows in a solenoid, contact is made inside a switch or motor winding are good.(that it is in fact making a complete circuit). A continuity test is performed by devices that can be used to perform continuity tests include multi meters which measure current and specialized continuity testers which are cheaper, more basic devices, generally with a simple light bulb that lights up when current flows. SEE: Electrical Fundamentals Course When a bad motor winding cannot be found by a physical inspection, many times an ohmmeter may show that there is a defective winding. Read more: How to Test Electric Motor Windings Ohmmeter usages. While the ohmmeter may not show potential failures, it can be used to determine if the windings are good or bad.

e between the dryer and the wall outlet should be either the foil type or the aluminum flexible duct (most preferred). Do not use the plastic or vinyl. Concealed ducting must be rigid metal (galvanized or aluminum) duct. Duct joints shall be installed so that the male end of the duct points in the direction of the airflow. Joints should be secured with metal tape (not duct tape). Do not use rivets or screws in the joint or anywhere else in the duct as these will encourage lint collection. Length of concealed rigid metal ducting shall not exceed 35 feet (25' for IRC). Deduct 5 feet from the allowable length for every 90 degree elbow and two and a half feet for every 45 degree fitting (the Dryer-Ell is an exception under 2006 IRC Section M1502.6, 2009 IMC Section 504.6.4 and 2009 IRC Section M1502.4). These lengths may vary per local codes and dryer manufacturers recommendations. The maximum length of a clothes dryer exhaust duct shall not exceed 25 feet (7,620 mm) the dryer location to the wall or roof termination. The maximum length of the duct shall be reduced 2.5 feet or each 45-degree (0.8 rad) bend, and 5 feet (1,524 mm) for each 90-degree (1.6 rad) bend. The maximum length of the exhaust duct does not include the transition duct. Dryer venting shall be independent of any other systems (chimneys or exhaust vents). Courtesy of InterNACH
Never assume the electricity is off. Before servicing an electrical device, disconnect it from its electrical source either by unplugging the appliance, or turning off the power at the breaker fuse box. Mark the service panel with a note so that no one will restore power while you are working. After turning off the power to the circuit, test the circuit to be certain that there is no power before attempting service.
