Parts for Whirlpool RM978BXVN1: 07 - Microwave Electrical Parts

This fuse holder secures and connects a replaceable inline fuse to the appliance's electrical circuit, restoring overcurrent protection and helping prevent damage from short circuits or power surges. What it does:

• Holds and connects a replaceable fuse in the appliance's electrical circuit
• Completes the fuse's electrical connection so current flows through the protective element
• Replaces a cracked, burnt, or loose holder that causes intermittent power or blown fuses
• Helps restore proper overcurrent protection when the fuse itself is intact

• Disconnect power to the appliance before inspecting or replacing electrical parts.
• Inspect nearby wiring and connectors; replace any damaged components to ensure a secure connection.

This time-delay fuse protects the appliance's power circuit by opening when current exceeds a safe level while tolerating brief inrush current. Replacing a blown fuse can help restore power once the root cause is corrected. What it does:

• Protects the line and control circuits from shorts and overloads
• Time-delay design helps prevent nuisance opening during startup surges
• When open, the unit will be completely dead—no display, lights, or response
• Repeatedly opening usually indicates an unresolved electrical fault that needs diagnosis

• 1 time-delay fuse

• Disconnect power at the breaker before servicing; some appliances can retain dangerous high voltage
• Replace only with the same type and rating specified by the manufacturer
• Inspect the fuse holder and wiring for heat damage or loose connections before reassembly
• If the new fuse opens immediately, stop and diagnose the underlying cause; never bypass or upsize a fuse

This latch knob screw secures the latch knob to its shaft on compatible appliances. Replace a missing, stripped, or rusted screw to restore a firm, reliable attachment and proper latch/knob operation. What it does:

• Attaches the latch knob securely to the latch mechanism/shaft
• Helps maintain proper door latch engagement and knob control
• Common fix for a loose, wobbly, or falling-off knob
• Replaces a lost, corroded, or cross-threaded screw

• 1 latch knob screw

• Disconnect power and allow the appliance to cool completely before servicing
• Align the knob on the shaft and start the screw by hand to avoid cross-threading
• Tighten with the correct screwdriver; do not overtighten to prevent damage
• The latch engages and releases smoothly after installation
