ProblemPossible CauseSolution
Unit will not turn on.• Power cord unplugged.• Ensure power cord is firmly plugged into outlet.
• Blown fuse or tripped circuit breaker.• Replace blown fuse; reset tripped breaker.
• Electrical power low (“brown out").• Low voltage protection prevents operation if supply voltage drops below 103.5 VAC for 115 VAC units or 197 VAC for 208/230 VAC units. Contact local electric utility if supply voltage is low.
• Electrical power outage.• Contact local electric utility.
Unit does not adequately cool (or heat) area.• Dirty air filter.• Remove and clean air filter. NOTE: Do not operate air conditioner with filter removed.
• Room or area not sealed.• Close all doors and windows in area. Close all air vents and ducts in area.
• Vent Control in EXHAUST position.• Vent Control should be in NORMAL position whenever air conditioner is in cooling or heating mode.
• Airflow to or from unit blocked.• Remove any obstruction to airflow from air discharge vent or return air vent on unit.
• Unit improperly sized for room or area.• Reduce area being conditioned (close doors or otherwise isolate area).
• Temperature control not properly set.• Turn temperature control to more comfortable setting.
Mounting support cannot be installed.• Window has storm window frame.• Window frame can be modified or if storm window frame must be removed.
Odors in cooling.• Formation of mold, mildew, or algae on wet surfaces.• Clean unit thoroughly.
• Place algaecide in base pan.
Odor in heating.• Caused by dust accumulation; normal whenever heater is first used and when heater has not been used for a period of time.• Odor will dissipate after heater cycles on and off several times.
Unit noisy.• Unit improperly installed, causing vibration when operating.• Review installation procedures. Ensure all mounting hardware is tight and secure.
• Water noise whenever fan runs.• Normal, especially during periods of high humidity.
• Loose screws or parts.• Remove chassis from outer case. Check for loose or missing screws. Tighten or replace as required.
