Kenmore Air Conditioner 580.74085400 (58074085400, 580 74085400) Parts

This replacement frame is a structural component that supports and aligns adjoining panels and hardware in your appliance. Replacing a cracked or warped frame restores a secure fit, reduces vibration, and keeps panels and trim seated correctly.

• Provides rigid mounting and alignment for the associated panel or assembly
• Keeps screws, clips, and trim in position to prevent looseness or rattling
• Helps maintain proper clearances so doors or panels open and close smoothly
• Common signs of failure: cracked plastic, broken tabs, visible gaps/misalignment, or a panel that won't stay attached

• Disconnect power to the appliance before servicing
• Note fastener locations and retain all screws/clips to transfer to the new frame
• Inspect mating panels and clips; replace any damaged retainers before reassembly
• Tighten fasteners evenly and avoid overtightening to prevent cracking the new part

This isolator routes microwave energy between the magnetron and waveguide to help protect components and maintain consistent heating performance. Replacing a failed isolator can restore reliable cooking and help prevent further high-voltage damage. What it does:

• Directs RF energy from the magnetron into the waveguide/cavity
• Helps protect the magnetron by reducing reflected energy
• Aids in preventing arcing or burn damage in the waveguide area
• Common symptoms of failure: no heat or uneven heating, loud humming/buzzing, visible arcing/burn marks near the waveguide

• 1 isolator

• Disconnect power and discharge the high-voltage capacitor before servicing; risk of electric shock
• Handle waveguide components carefully; avoid contaminating RF surfaces and note exact orientation
• Take photos of the original setup to match positioning and fastener locations

This NTC thermistor assembly senses temperature and sends readings to the control board so the appliance maintains the correct cooling cycle. It replaces a failed or intermittent temperature sensor to restore proper temperature regulation. What it does:

• Measures compartment temperature and relays the signal to the control board
• Helps the appliance decide when to run compressor and fans for stable cooling
• Commonly replaces units that cause incorrect temperature readouts, excessive frost, or compressor cycling
• Works as the OEM temperature-sensing element in the appliance's refrigeration system

• Disconnect power before accessing internal components to avoid shock
• Handle sensor and wiring gently; avoid bending or crimping the thermistor tip
• Verify connector seating and routing to prevent pinched wires or interference with moving parts

This remote controller assembly is the complete handheld control used to operate compatible appliances, restoring lost or damaged remote control functions for convenient, wireless operation. What it does:

• Sends the appliance's infrared/remote commands to control settings and cycles
• Replaces a broken, unresponsive, or missing remote to regain full remote functionality
• Helps resolve symptoms like no response from remote, intermittent command reception, or damaged buttons
• Works as the user-facing control interface for selecting modes, temperatures, or timed functions

• One remote controller assembly (as shown)

• Replace with the power source removed and follow the appliance manual for pairing or setup
• Handle electronic components carefully; avoid moisture and static discharge
• If the original remote used batteries, install fresh batteries and test operation after replacement
• If commands still fail, verify line-of-sight to the appliance and that the appliance receiver is powered
