    8.0 Troubleshooting WARNING - A POTENTIAL ELECTRICAL SHOCK HAZARD EXISTS. Some of the troubleshooting checks may require gaining access to the dryer’s electrical enclosure(s) while the power supply is energized and should be performed by a qualified electrical technician. WARNING - Before performing any electrical or mechanical repairs or maintenance, or removing or disassembling any component, be sure to de- energize and depressurize the dryer.
