Check power supply and connections, verify proper voltage, inspect capacitor if applicable, test motor windings for shorts or opens, lubricate bearings if possible, replace motor assembly if diagnostics confirm failure.
Coil freeze damage
Symptoms:
Water leakage, reduced heating/cooling capacity, visible coil damage, ice formation during heating operation
Solution:
Inspect coil for physical damage, test for leaks using pressure test, verify adequate water flow, check freeze protection settings, ensure proper glycol concentration in colder climates, repair or replace damaged coil.
Condensate overflow
Symptoms:
Water damage near unit, water stains, mold growth, musty odors, condensate safety switch tripping
Solution:
Clean drain pan and condensate line, verify proper slope of drain line, ensure proper trap installation, check condensate pump operation if equipped, treat drain pan with algaecide tablets to prevent future blockages.
