Parts for Jenn-Air JMW8530CAB: 04 - Internal Controls Parts

This safety thermostat monitors internal temperature and opens the circuit if the appliance overheats. Replacing a failed high-limit thermostat restores heat and helps protect controls, wiring, and nearby components from thermal damage. What it does:

• Monitors temperature and interrupts power to the heating circuit if an unsafe temperature is reached
• Helps prevent overheating damage to internal components
• When failed open, can cause no heat or cause the unit to shut off during high-heat operation
• At room temperature it should read closed/continuous; an open reading indicates replacement is needed

• 1 high-limit thermostat

• Disconnect power at the breaker (and shut off gas supply if applicable) before servicing
• Access location varies by model; commonly mounted to the oven cavity, plenum, or rear panel
• Transfer wires one at a time and mount the thermostat flush to its surface or bracket
• After replacement, verify proper airflow/cooling and address any root causes of overheating

This factory fastener secures panels, trim, or brackets on your appliance. Replacing a missing or stripped screw restores a snug, rattle-free fit and keeps components aligned for proper operation and a clean, finished appearance.

• Fastens exterior panels, trim pieces, or internal brackets to the appliance chassis
• Replaces lost, damaged, or stripped hardware
• Helps prevent vibration, rattling, and gaps between parts
• Common signs you need this screw: missing hardware, loose or misaligned panel/trim, stripped head or threads

• Disconnect power before servicing; also shut off the gas supply
• Use the correct driver; start the screw by hand to avoid cross-threading
• Tighten snugly—do not overtighten to prevent stripping or cracking adjacent parts
• Repair or replace the mounting point before installing

This 20-amp circuit breaker restores overcurrent protection to the appliance's electrical circuit, helping prevent damage from short circuits or overloads. It replaces a worn or tripped breaker so the appliance can receive proper power. What it does:

• Acts as an overcurrent safety device that trips when current exceeds safe limits
• Protects wiring and components from damage caused by overloads or short circuits
• Common symptom: appliance won't power on or stops powering intermittently
• Common symptom: breaker repeatedly trips during normal operation

• Disconnect power at the house breaker before inspecting or replacing the part
• Handle terminals carefully; ensure connectors are fully seated and tight
• Replace with the exact part number for fit and proper electrical rating
