Improperly mounted or loose cabinet parts. Check that compressor mounting parts are not missing. If unit operates, replace thermostat.Р вЂќР’В¬heck that compressor grommets have not deteriorated. Place jumper across thermostat terminals to check if unit operates. Restricted or low air flow through condenser coil.Р вЂќР’В¬heck for proper fan speed or blocked condenser.Р вЂќР’В¬heck for kinked discharge line or restricted condenser. Air conditioner should be on separate circuit for proper voltage, and be fused separately.Р вЂќР’В¬heck by substituting a known good capacitor of correct rating.
