TROUBLESHOOTING TIPS Troubleshooting tips ... Before you call for service Save time and money! Review the charts on the following pages first and you may not need to call for service. Problem Fan/Light does not operate when button is turned ON Loud or abnormal airflow noise Possible Cause A house fuse may be blown or a circuit breaker tripped. Wrong duct size used in installation. Fan fails to circulate air or moves air slower than normal and/or fan is making loud or abnormal airflow noise Obstructions in duct work. Damper blade on wall or roof cap may not be open. Metal grease filter and charcoal filter (if present) may be dirty. Insufficient makeup (replacement) air Fan keeps going off and The motor is probably overheating and on turning itself off. This can be harmful to the motor. What To Do Replace fuse or reset circuit breaker. This unit requires 8" ducting to perform optimally. Using smaller duct pipe will cause reduced venting. Minimize the duct run length and number of transitions and elbows. GE Appliances service technicians cannot correct this issue if installed improperly. Make sure nothing is blocking the vent. Make sure your wall or roof cap has a blade or door. Make sure damper swings freely. Damper blades may flip over and will not fully open when this happens. Adjust to original position. Clean the metal grease filter and replace charcoal filter (if present). See Care and Cleaning. Sufficient makeup (replacement) air is required for exhausting appliances to operate to rating. Check with local building codes, which may require or strongly advise the use of makeup air. Visit GEAppliances.com for available makeup air solutions. Check to be sure the filters are clean. If off and on cycling continues, call for service. 49-2000492 Rev. 2 29
