How to fix a ForestAir FA-H09-A20TL Air Conditioner that won't turn on?

If your ForestAir Air Conditioner isn't turning on, it could be due to several reasons. First, check for a power outage and wait for the electricity to be restored. A fuse may have tripped, so verify the fuses and circuit breakers. Also, check the connections and plug to ensure they are secure. When changing operation modes, remember that a 3-minute protection delay is triggered to protect the compressor. If the Timer function was unintentionally set, cancel it, or wait for the unit to start at the set time.
