Flame Sensor Parts

Refrigerator not cooling or freezing over? This defrost thermostat monitors evaporator temperature to control defrost cycles. Easy DIY fix restores cooling.

This sensor detects moisture levels inside the microwave cavity during cooking and communicates with the control board to adjust cook times automatically. It is a key component for auto-cook and sensor-reheat functions. Replace this sensor if the microwave fails to properly detect doneness, overcooks or undercooks food on sensor settings, or displays a sensor error code.

This defrost thermostat helps control the refrigerator/freezer defrost cycle by sensing evaporator temperature and allowing the heater to run when frost removal is needed. Replaces a failed thermostat to restore normal defrost operation. What it does:

• Closes when the evaporator is cold so the defrost heater can run, then opens when the coil warms to stop defrosting
• Helps prevent excessive frost and ice buildup on the evaporator coil
• Common symptom: visible frost or ice on evaporator, excessive frost buildup, or defrost heater running constantly/ not at all
• Works with the defrost system to maintain efficient cooling performance

• One defrost thermostat

• Disconnect power to the appliance before starting any repair
• Mount on or near the evaporator coil as originally installed; secure wiring away from moving parts
• Inspect the harness and connector for damage; replace if corroded or brittle
• Test for continuity with a multimeter to confirm thermostat function before and after installation

Fix uneven cooking or incorrect oven temperatures with this temperature sensor. Detects cavity temperature for accurate bake cycles. Easy DIY repair.

This switch sensor is a direct-replacement sensing device that detects the position/state of a moving component and sends that signal to the appliance control for reliable operation. It restores correct sensing when the original fails. What it does:

• Detects and reports a component's open/closed or engaged/disengaged position to the control
• Helps the appliance start and change cycles only when the mechanism is in the correct position
• Can resolve symptoms such as no response from the control, intermittent operation, or cycles that won't advance
• Provides a direct electrical/mechanical interface between the moving part and the control system

• One switch sensor

• Disconnect power to the appliance before starting any repair
• Match this part number to the failed sensor before installing
• Handle wiring and connectors carefully; avoid forcing tabs or pins
• Test operation after installation and restore power only when all connections are secure

Dryer overheating or shutting off? This safety thermostat detects excessive heat and cuts power to prevent thermal damage. Direct replacement part.

Washer not heating or cooling properly? This thermistor temperature sensor assembly measures internal temps and sends readings to the control board.

This thermistor is the refrigerator temperature sensor that helps the control board monitor and regulate cooling. Replacing a faulty sensor restores accurate temperature readings and consistent cooling performance. What it does:

• Measures internal refrigerator/freezer temperature and sends readings to the control board
• Helps the control board adjust compressor and fan operation for stable temperatures
• Can cause incorrect temperature display or uneven cooling when it fails
• Linked to excessive running, frequent defrost cycles, or poor cooling performance

• Disconnect power to the appliance before servicing to avoid shock or damage
• Handle the sensor and wiring harness carefully; avoid kinking or damaging the lead
• Ensure the connector is fully seated and any mounting clip or bracket is secured
• Some panel removal may be required; follow for access and reassembly

Fix a dryer that won't heat properly or overheats. This cycle thermostat regulates temperature during heating cycles. Easy DIY repair in under an hour.

Dryer won't heat or overheats? This thermostat regulates temperature during drying cycles. Easy 15-minute DIY fix restores proper heat control.

Fix dishwasher heating issues with this thermistor and high-limit thermostat assembly. Restores proper temperature control and prevents overheating.

This is a replacement electrical fuse used in select Bosch appliances to protect internal circuits by opening the circuit if an overload or fault occurs. It restores proper safety protection when the original fuse is blown. What it does

• Acts as an overcurrent/thermal protection element for control and power circuits
• Prevents further electrical damage by interrupting power when a fault is present
• Common symptom of a blown fuse: appliance has no power or certain functions won't operate
• May be checked when the appliance is completely unresponsive or specific components do not receive power

• One replacement Fuse 4 (mdl 4)

• Disconnect power to the appliance before inspecting or replacing the fuse
• Replace only with the exact part specified for your model; do not bypass the fuse
• If the replacement fuse blows again, stop use—repeated failures indicate a deeper electrical problem
• Wear appropriate safety gear and follow for access instructions

Dishwasher not heating or shutting off mid-cycle? This thermostat regulates water temperature. Direct replacement part with moderate difficulty install.
