Assy-Case Sensor Parts

This safety device protects the compressor by interrupting power if it overheats or draws excessive current. Replacing a weak or failed protector restores reliable starts and helps prevent nuisance shutdowns and compressor damage.

• Opens the compressor circuit during overheat/overload to prevent motor damage
• Common symptoms include: compressor won't start, clicks and briefly hums, or starts then quickly shuts off
• Can contribute to poor cooling while fans or controls still operate
• Visual clues may include heat discoloration or damaged terminals at the protector

• Disconnect power before servicing; capacitors in the system can retain a charge—discharge safely
• Access the compressor terminal cover; note wire locations and remove the old protector
• Inspect terminals/connectors; replace any burnt or loose spade connectors for a secure fit
• Fully seat the new protector on the compressor terminal and reconnect wires firmly; check any companion start relay or capacitor if symptoms persist

This temperature sensor (thermistor probe) monitors internal refrigerator temperatures and sends readings to the control board so cooling cycles respond correctly. Replacing a faulty sensor helps restore accurate temperature control and more consistent cooling. What it does:

• Senses cabinet temperature and provides a variable resistance signal to the control board
• Allows the refrigerator to cycle the compressor and fans based on actual temps
• Commonly linked to symptoms like temperature fluctuations, overcooling or warming, long run times, or cooling-related error codes
• Works as the temperature feedback element for fresh food/freezer systems

• Disconnect power to the appliance before starting any repair
• Handle probe and connector wiring carefully—do not kink or overly bend the sensor element
• Route and secure wiring per service manual or parts diagram to avoid contact with moving parts or heat sources

This thermostat is the temperature control switch that helps regulate your appliance's internal temperature for proper operation and food safety. It replaces a failed or faulty control to restore consistent cooling performance. What it does:

• Senses interior temperature and cycles the compressor or heating element to maintain set temperature
• Stops cooling or heating when the thermostat fails open, or causes overcooling when it fails closed
• Commonly replaced for inconsistent temperatures or an appliance that runs constantly
• Works as the user-controlled temperature regulator in the appliance's control system

• Disconnect power before starting any repair to reduce shock risk
• Handle mounting hardware and wiring carefully; note wire locations before removal
• Test operation after install by setting temperature and confirming normal cycling

This clip-mount bimetal defrost thermostat senses evaporator temperature and closes to allow the heater circuit during defrost cycles, helping prevent ice buildup on the evaporator. It restores proper defrost operation when the thermostat has failed. What it does:

• Opens and closes based on evaporator temperature to control the defrost heater circuit
• Allows the defrost heater to run when ice buildup requires melting
• Common symptom: excessive frost or ice on the evaporator coils
• Common symptom: defrost cycle not activating or freezer running intermittently

• One bimetal defrost thermostat with mounting clip

• Disconnect power to the appliance before servicing to avoid shock
• Replace only when the original defrost thermostat is faulty; handle the sensing element carefully
• Ensure the thermostat is securely clipped to the evaporator tube and wiring connections are tight

This probe thermistor monitors interior temperature and sends readings to the control board so your appliance can maintain the correct cooling cycle. It replaces a failed or inaccurate sensor to help restore proper temperature regulation. What it does:

• Senses air or evaporator temperature and reports it to the control module
• Commonly related to warm/freezing issues, incorrect temperature readings, or erratic cycling
• Used by the control system to trigger fans, defrost, and compressor operation as needed
• Works as a direct replacement for the listed OEM temperature probe

• Disconnect power before replacing to avoid shock or damage
• Handle the sensor tip and wiring gently to avoid damage to the element or insulation
• Route and secure the wiring so it does not contact moving parts or hot surfaces

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

This safety thermostat detects excessive heat and stops power to the heating system to help prevent overheating and thermal damage. It's a direct-replacement safety cut-out for compatible GE appliances. What it does:

• Opens the circuit when internal temperatures exceed safe limits to shut off the heating element
• Helps prevent overheating, reducing risk of component damage or fire
• Restores normal operation only after cooldown or replacement, depending on design
• Commonly used on ovens, ranges and other heating appliances as a thermal safety device

• One safety thermostat

• Disconnect power to the appliance before servicing to avoid shock or injury
• Note and mark wiring locations or take a photo before removing the old thermostat
• Replace only with the exact part; improper parts may void safety features

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

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
