If the microwave oven does not operate: • Check that a household fuse has not blown, or that a circuit breaker has not tripped. Replace the fuse or reset the circuit breaker. If the problem continues, call an electrician.
DUCTING DESIGN SPECIFICATIONS This section is intended for architectural designer and builder/contractor reference only. NOTES: • Duct materials needed for installation are not provided with microwave oven. • We do not recommend using a flexible metal Duct. • To avoid possible product damage, be sure to vent air outside, unless using recirculation installation. Do not vent exhaust air into concealed spaces, such as spaces within walls or ceilings, attics, crawl spaces, or garages.
Recommended Vent Length A 3 1/4" x 10" (8.3 x 25.4 cm) rectangular or 5" (12.7 cm) / 6" (15.2 cm) diameter round duct should be used. The total length of the vent system including straight duct, elbow(s), transitions, and wall or roof caps must not exceed the equivalent of 140 ft (42.7 m) for either type of vent. For best performance, use no more than three 90° elbows. To calculate the length of the system you need, add the equivalent lengths of each duct piece used in the system.
