A00099902 Frigidaire Dishwasher Door Latch is a replacement door latch assembly designed for Frigidaire dishwashers; itâ is â˘indeed an electromechanical/mechanical component that secures the appliance door and contains the actuation mechanism and associated switches used to signal the control system. The assembly typically includes the latch striker, an actuator, one or more microâswitches or âinterlock contactsand the mounting features that fasten it âŁto the door and cabinet. âConstructed to interface⢠with the door edge âand front frame, the part⤠is intended to provide both the mechanical retention required during operation and the electrical input needed by the control electronics.
Within the appliance the latch serves two primary purposes: it mechanically secures âŁand aligns the door to maintain the integrity of the door seal and it provides electrical interlock signals âto the control board so wash cycles only run when â˘the door⣠is closed. â˘The latch interacts directly â˘withâ theâ door sealing system, the door hinges and strike, the control board or user interface through its⢠microâswitchesand indirectly with safety and functional systems⢠such âas the water inlet, pump/motor control âand timer âsince those systems⤠depend on a confirmed doorâclosed state. A faulty latch can therefore cause cycleâ refusal, intermittent operation, water leakageor unsafe conditions if the interlock⤠function is compromised.
In the article that follows you will find a technical overview of the A00099902 âpart including its mechanical and electrical function, guidance â¤on model compatibility and how to confirm correct replacement fit, common âfailure⤠symptoms to watch forand âpractical troubleshooting steps such as continuity testing of switches, mechanical inspection and alignment checks. Replacement considerations covered includeâ safety precautions (power âŁisolation),⣠required tools âand disassembly sequence, âtips for verifying proper engagement and seal integrity after installationand â˘notes on comparing⣠OEM versus aftermarket options for fit and interchangeability. The aim is âto provide technicians, engineers and informed applianceâ owners with the diagnostic and procedural context needed to evaluate, test and replace the latch reliably and safely.

Function and Role of the Dishwasher Door Latch Assembly in Safety Interlocks and âWater Sealing
The A00099902 Frigidaire Dishwasher Door Latch is a combined mechanical and electrical assembly thatâ serves as⤠both the door âcatch and âthe primary safety interlock for the appliance. Mechanically,the latch engages âa striker on the door to apply controlled compression to the⣠door gasket,forming the primary⢠water seal across the front edge of theâ tub. Electrically, the assembly contains one or more microswitches or â¤a plunger switch âthat must indicate a closed-door condition to the control board⣠before the pump, heaterand dispenser⤠will be enabled.replacement or troubleshooting requires âŁmatching the mounting footprint, connector typeand âactuator geometry to ensure proper striker alignment and consistent switch â˘actuation; mismatches can allow the door to appear âclosed while failing toâ produce reliable switch continuity or adequate gasket compression.
Technicians and owners typically diagnose latch-related faults by observing symptoms such as no-start conditions, intermittent cycle cancellation, audible beepsor water pooling at the front of the cabinet. practical checks include verifying microswitch continuity with a multimeter while operatingâ the latch, inspecting the striker for wear or misalignment, âmeasuring gasket âcompression across the door edgeand confirming that the electrical connector pins and â˘wiring harness are intact. Common features and behaviors to inspectâ include:
- Switch actuation: consistent continuity when latched and open when released.
- Mechanical engagement: smooth⣠catch/release with no âexcessive play or binding.
- Gasket compression: even contact across the front edge when latched.
- Mounting compatibility: correct screw locations and connector type for the model.

How the⢠A00099902 Frigidaire Dishwasher Door Latch Interfaces Internally with the Door Switch, Strikeand⤠control board
The A00099902 Frigidaire Dishwasher Door Latch combines a mechanical striker engagement withâ an electrical switch used by the control board to confirm the door is closed and ready for a wash cycle. Mechanically, the striker on the door engages a plunger⤠or hook in the latch body; this both holds the door shut and positions an internal actuator so the electrical switch changes state. Electrically, that switch is typically a simple closed/open contact (microswitch or similar sensor) that the control board monitors: a closed contact⤠tellsâ the board the door is secure and permits motor/heater relays to energize, while an open contact prevents cycle start or causes a door-fault error. Misalignment, worn striker componentsor a â˘failed internal switch will produce intermittent open signals âŁor a persistent “door open”⢠fault even though the door âappears latched.
For service âŁand compatibility, verify that theâ replacement⣠latch matches the original â˘mounting points and connector pinout before installation; incorrect alignment or wiring can cause false faults or âŁprevent⣠the control board from locking out during high-heat cycles.Troubleshooting typically involves a visual â¤inspection of the⢠striker engagement and gasket clearanceand an â¤electrical check with a multimeter across the latch’s switch terminals to confirm continuity⢠when the latch is actuated. Technicians should âŁalso inspect the harness at the control board for corrosion or â˘loose pins, since the latch only reports the door state-the board performs safety interlocks and may log â˘related error codes that help isolate whether âthe issue is⣠mechanical, electrical at the latchor a control-board input fault.
- Mechanical engagement: âstriker-to-plunger alignment and latch retention force
- Electrical⣠signal: âŁswitch open/closed state reported to control board
- Connector âinterface: multi-pin⢠harness continuity and pinout compatibility
- Service checks: actuator continuity test, visual alignment, harness inspection
| Item | Description |
|---|---|
| Mechanical interface | Striker engages the latch plunger/hook to physically secure âŁthe door⢠and position the switch actuator. |
| Electricalâ switch | Internal contact that changes state when latched; the control board reads this as Door Closed/open. |
| Control board connector | Multi-pin harness that carries⤠the door-switch signal (verify⢠pinout and continuity⣠when replacing). |
| Common symptom | Dishwasher will not start or displays door-fault codes if latch switchâ fails or âŁalignment is off. |
Common Failure Symptoms and Electronic/Mechanical Diagnostic Indicators of Door Latch â¤Faults
The A00099902 Frigidaire Dishwasher Door Latch is a combined mechanical catch andâ electrical interlock that secures the door and provides the control boardâ with a definitive door-closed/locked signal. Mechanically, the latch engages a striker on⢠the door to hold the door shutâ during fillâ and wash cycles; electrically, it contains âone âor more microswitches â˘that change state when the latch is fully engaged. â˘Compatibility depends on⤠matching the mounting tabs, actuator geometryand connector pinout to the dishwasher model-physically similar latches can fail even â˘when the connector fits, so confirm the part number and terminal layout against the service sheet âbefore replacing. typical failure modes âare plastic housing or pawl breakage, misalignment of the strikeror switch contact wear that leads to intermittent or no âelectrical⢠continuity when the door is apparently closed.
- Dishwasher will not start or will⣠stop mid-cycle while the door appearsâ closed (mechanical latch not holding orâ switch open).
- No audible click from the latch when closing the door (failed microswitch or broken actuator).
- Intermittent door-closed signal toâ the control board causing error/lock indicators or repeated attempts to lock.
- Visible cracks,broken tabs,or excessive play at the latch mounting points (mechanical failure).
Technicians diagnose â¤latch faults by combining visual/mechanical inspectionâ with basic electrical⤠tests. With mains power removed, check for free movement and broken plastic;â then test âcontinuity across⤠the latch switches with â˘a multimeter-expect near 0 Ί between common and closed terminals when latched and open/infinite resistance when unlatched. Under live conditions (refer to the appliance wiring diagram), confirm the control board is receiving the expected latch signal and â˘that any lock solenoid or motor (if present) actuates and returns. if continuity and actuator motion âŁare correct but the control still reports a door fault, verify connector wiring â˘and board input circuitry before replacing the latch assembly.
| Item | Description |
|---|---|
| Continuity (door closed) | Approximately 0-5 Ί between COM and NO/closed terminal |
| Continuity (door open) | Open/infinite resistance âbetween COM and NO; continuity to NC if present |
Replacement âConsiderations âand Step-by-Step Installation Requirements for the Door Latch âAssembly
The A00099902â Frigidaire Dishwasher Door Latch secures the door during wash cycles âand provides âŁthe mechanical actuation for the door-interlock switch that allows the control⢠board to initiate and terminate operation.The assembly typically includes the plastic latch body, a metal striker or catch on the door frameand an electrical microswitch âŁor connector â¤that signals the control system; wear of the plastic engagement surfaces or contamination of the striker can⣠cause intermittent door-closed signals, leaksor failure to start. Verify that replacement units match âthe original mounting hole spacing, connector pinoutand⤠actuator orientation before installation to ensure compatibility with the door inner panel, strike plateand existing⣠wiring harness on your Frigidaire model.
Installation requires simple hand tools and controlled reassembly to preserve door alignment and switch integrity: disconnect power and,â if accessible, the water supply, remove theâ inner door access coverand carefully note or mark connector positions before disconnecting the harness. During reinstallation align the latch so the striker engages smoothly across the âfull swing of the door, torque sheet-metal screws snugly âto avoid strippingand â¤confirm electrical continuity of the door-closed âswitch with a multimeter prior to full reassembly. âAfter the latch is âŁinstalled, run a short diagnostic or speedy wash cycle to⤠verify the door lock signal under load and inspect the door seal compression around the perimeter to confirm⢠no new leak paths were introduced.
- Disconnect power and remove inner door access âpanel.
- Document connector orientation, unplug harnessand â˘remove latch âŁmounting screws.
- Compare new A00099902 Frigidaire Dishwasher Door Latch to âŁthe old part for pinout and mounting alignment.
- Install new latch, hand-tighten screws, reconnect harness, â¤and check switch continuity.
- Reassemble panel,â check door strike engagement over full swing, â¤and run a test cycle.
