Assy-Case Sensor Parts

This temperature sensor (thermistor) detects internal appliance temperature and sends readings to the control board so the unit maintains proper cooling. Replacing a failing sensor restores accurate temperature monitoring and helps prevent spoilage. What it does:

• Measures internal temperature and provides a resistance-based signal to the control board
• Helps the control system regulate compressor and defrost cycles
• Commonly causes warm or fluctuating temperatures, prolonged cooling, or temperature-related error codes when failing
• Works as a direct-sensing temperature input — not a user control or switch

• One temperature sensor/thermistor (single part as shown)

• Unplug the appliance or switch off power at the breaker before servicing
• Handle the sensor and its thin leads carefully to avoid damage during removal and installation
• Route and secure wiring so it does not contact moving parts or sharp edges

5 A, 125 V electrical fuse that restores circuit protection when the original fuse is blown. Replacing the failed fuse helps prevent further electrical damage and can restore normal appliance operation. What it does:

• Provides overcurrent protection for the appliance circuit to stop excessive current flow.
• Replaces a blown or open fuse that prevents the appliance from powering up.
• Common symptom: appliance has no power or a circuit/component won't operate.
• Common symptom: intermittent power or a fuse that visibly shows a blown element.

• Always disconnect power (unplug or shut off breaker) before inspecting or replacing the fuse.
• Replace only with the exact rated fuse (5 A, 125 V) and part number to maintain proper protection.
• Do not bypass the fuse or use makeshift substitutes — that can cause fire or equipment damage.

If your air conditioner won't start or shuts down unexpectedly, a failed compressor overload protector is often the cause. This simple swap restores starts.

This fixed thermostat monitors and limits temperature to protect the appliance's system and components. It's a simple, non-adjustable sensor/limit switch used where a set cutoff temperature is required for safe operation. What it does:

• Opens or cuts power when the monitored temperature reaches its fixed limit to prevent overheating
• Helps stop continuous heating cycles caused by a failed control or sensor
• Commonly used as a safety cutoff in temperature-control circuits
• Can resolve symptoms like persistent overheating, failure to stop heating, or temperature-related shutdowns

• One fixed thermostat (single unit)

• Disconnect power before inspecting or replacing the thermostat to avoid shock or damage
• Handle gently; avoid bending terminals or stressing sensing elements

Dryer not heating or leaving clothes damp? This thermostat with sensing cable regulates temperature and prevents overheating. Easy DIY repair part.

A 15 amp cartridge fuse that protects appliance electrical circuits from overcurrent, helping prevent damage to controls and components. Fits into inline fuse holders or boards where that specific fuse rating is required. What it does

• Interrupts circuit power when current exceeds 15 amps to protect wiring and electronics
• Commonly linked to symptoms like no power to controls, unresponsive display, or appliances that won't start
• Designed to be replaced when visibly blown or when continuity test fails
• Works as the exact rated safety fuse specified for compatible appliances

• One 15 amp cartridge fuse

• Disconnect all power to the appliance before accessing or replacing the fuse
• Replace with the identical fuse type and 15 amp rating only; do not substitute different ratings
• Handle carefully and mount fully seated in its holder or on the PCB as designed
• If the new fuse fails again immediately, stop — repeated failures indicate underlying electrical faults

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 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

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.

This flow meter measures the volume of water passing through the refrigerator's water dispensing system. It sends signals to the control board to accurately track water usage and control dispenser operation. Replace this part if your water dispenser delivers inconsistent amounts of water, fails to shut off properly, or if the dispenser display shows inaccurate readings.

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.
