Hotpoint HTS18GBSSS 18 cu ft Top-Freezer Refrigerator with Adjustable Wire Shelves MECH-08 Error Fix: Interior Light Not Working

Error code MECH-08 on the Hotpoint HTS18GBSSS 18 cu ft Top-Freezer Refrigerator with Adjustable Wire Shelves means: Interior Light Not Working. The refrigerator interior light does not turn on when the door is opened — the most common cause is a burned-out bulb; Hotpoint refrigerators typically use a standard 40-watt appliance bulb (A15 size with an intermediate or standard base); always use an appliance-rated bulb designed to handle the cold temperature; if a new bulb does not fix it, the door switch (usually a small plunger-style switch in the door frame that is depressed when the door closes) may have failed — test for continuity with the plunger released (door open position); in rare cases, the light socket itself may have corroded

The most successful fix is "Test and Replace the Door Switch" (medium difficulty, ~30 minutes). Estimated DIY cost: $10-$20. HomeMD has 2 community-ranked fixes for this error.
