3 catalogued root causes for this symptom: door_seal_leakage: Worn door seals let humid shop air into the booth during bake cycles; condensate forms on cold panels during cool-down. — insufficient_vapor_barrier: Insulated booth lacks a vapor barrier; humid shop air migrates to the cold wall cavity and condenses. — outside_dew_point_above_wall_temp: External dew point at or above 75F with poorly insulated walls, moisture condenses on the cold interior surface.. The diagnostic sequence below walks through isolating each in order.
