A00099902 Frigidaire⢠Dishwasher Doorâ Latch is an electromechanicalâ doorâ latching assembly designed for residential Frigidaire dishwashers; it â˘combines the mechanical catch thatâ secures â¤theâ door with one or more electrical â˘switches âthat signal the main control when the doorâ is closed and â˘latched. As a âreplaceable service part, the assembly is typically composed of a plastic â˘housing and âstriker â˘interface, aâ latch actuatorand one orâ more microswitches or contacts that⤠provide the closed/locked stateâ to the appliance electronics.
inside âthe appliance the door latch performs two primary functions: âit provides a positive âmechanicalâ hold to maintainâ a â¤watertight seal between the door and â¤tub during fill and wash⣠operationsand itâ provides an electrical interlock input to⤠the control board âso âcycles â˘and safety⤠functions (such as heating and pump operation) â˘proceed⤠only when the door is secured.â The latch interfaces âmechanically with the âdoor strike and gasket, âand electrically⢠with the âdishwasher’s wiring⤠harness and âcontrol PCB; failures or misalignment can therefore affectâ water containment,⤠cycle enablementand diagnostics reported by the machine.
This article explains⣠the latch’s â˘functional⤠design and â˘where A00099902 is âtypically used, outlines compatibility âconsiderationsâ across model familiesand describes common failure symptoms âŁtechnicians and owners âwill encounter. It will also cover diagnostic approaches to distinguish mechanicalâ wear⣠from â¤electrical switch faults, key troubleshooting checkpoints andâ test pointsâ to considerand practical replacement considerations such as connector and mounting⤠compatibility, sealingand selection between OEM and serviceâreplacement parts.

Function and Role of the Door Latch âassembly in âFrigidaire dishwashers
The A00099902 Frigidaire Dishwasherâ Doorâ Latch provides both a mechanical âŁclosureâ and an⤠electrical interlock for the dishwasher âdoor.⣠Its primary⣠mechanical role is âŁto draw the door â¤tightâ against the cabinet gasket to maintain a watertight â¤seal during fill⤠and wash phases,while the integrated switch⤠or microswitch signals⣠the control board that the door is âclosed â¤and latched. The assembly also âserves as a safety interlock that prevents the dishwasher â˘from starting or continuing a cycle if the door is⢠not⢠fully⣠engaged. In âpractice this means the latch must âŁhave correct alignment,intact striker engagement,and a reliable electrical connector so the⤠control receives a âstable closedâ circuit whenever⤠the⤠door is⣠latched.
Behavior and compatibility considerations affect diagnosis and replacement: intermittent â˘switch contact â¤will cause symptoms such as failure to start, mid-cycle pauses or abortsand, âin some cases, water on the floor â˘if the doorâ does ânot fully compress the gasket. Technicians⣠typically verify functionality by checking physical wear on⢠the⣠striker and plastic housing,confirming continuity acrossâ the âŁlatch switch while actuating the mechanism,and âinspecting the wire âharness pinoutâ and mounting points for model fit.â Common practical steps include âverifying â¤the part number against the appliance model, testing the⣠switch with a multimeter (continuity test)and confirming that replacement A00099902 fits the door â˘mounting pattern âand connectorâ to avoid mismatched actuationâ or improper sealing.
- Symptoms of latch âŁissues: no-start,intermittent stops,visible leaks,or door not staying closed.
- Diagnostic checks: visual wear inspection, continuity test âon the switchand verification of harness/connector pinout.
- Installation âchecks: proper striker alignment, secureâ mountingâ screwsand correct gasket compression.

How the⣠A00099902â frigidaireâ Dishwasher Door Latch Operates: Mechanical Engagement, Electrical Sensingand Control interface
The A00099902 âFrigidaire Dishwasher Door Latch is a combined mechanical â˘catch and electricalâ interlock⤠designed to secure the doorâ and provide⣠the control âboard with a definitive closed/locked signal. Mechanically, the assembly⤠uses⢠a spring-loaded âpawl⣠and â¤strike to pull the âdoor into theâ gasket and maintain consistent compression; wear on the pawl, weakened springsor a misaligned strike will prevent full engagement, leading to leaks or an inability⣠toâ start a â˘cycle.â The part isâ a direct-replacement style⢠latch for specific âFrigidaire âŁmodels and should be fitted so âthat â¤the latch âŁengages â˘smoothly without forcing – aâ small adjustmentâ to the hinge or strike often restores correct âŁalignment â¤and sealing in the field without âreplacing âother components.
Electrically, theâ latch contains one or âmore internal contacts that change state when the mechanical catch is⣠fully engaged; the dishwasher control monitors âthis contact as a safety interlock andâ will refuse to â¤energize heating or pump circuits â˘if⤠the contact is â˘open.⤠Technicians typically diagnose latch failures by confirming continuity across the switch with⣠the door⣠closed, checking for â¤proper connector voltagesâ during a start âattempt,â and inspecting for chafed wires or corrosion at âthe harness. Common practical checks include:
- Verify continuity across the switch⢠when â¤the latch is actuated.
- Confirm the control board is receiving the closed signal (measureâ at the âharness while actuating the latch).
- Inspect the latch for broken plastic components or compressed springs that prevent full mechanical engagement.

Diagnostic Indicatorsâ and âCommon Failure Symptoms Associated with the A00099902 Latch
The A00099902 Frigidaire Dishwasher Door Latch is aâ combined mechanical and electrical interface that âsecures⤠the door andâ provides the control â¤board with a positive closed-door â˘signal. Mechanically, âthe⢠latch⤠engages the strike on the tub âŁto hold the âdoor under gasket compression; electrically, âŁit typically âactuates a microswitch âor reed/contact sensor that completes the start/lock⢠circuit. Technicians should verify âŁfit and âŁswitch orientation against the appliance model number âŁbecause variations in mounting â˘boss, strike positionor switch âtype will affect compatibility even among â˘Frigidaire units; replacing only with the correct A00099902 or a confirmed equivalent prevents misalignment,⢠false⣠door-open indicationsand undue stress on the door hinges and âgasket.
Failures of this âŁlatch manifest as either mechanical âbreakage or loss of âelectrical continuity and each produces âdistinct symptoms that⤠guide diagnosis. âA cracked orâ deformed latch will let the door pop âopen, cause â˘leaks along the door perimeterorâ prevent proper gasket compression; an intact striker with a failed internal switch âwill still allow âthe doorâ to close and click butâ the⤠machine â˘will â˘refuse to start or âwill abort cycles intermittently because the control does not receive⣠a closed-door â¤input. Simple diagnostic steps include a visual inspection⤠for⣠deformationâ or wear, manual âactuation of the⣠latch while measuring continuity across the switch with a â¤multimeterand confirming that the striker and latch engage without excessive play; if⤠the⤠switch fails â¤to change state reliably⤠when the latch isâ engaged, the latch assembly should be replaced.

Q&A
What is the A00099902 Frigidaire dishwasher door latch and what⣠does âit do?
The â˘A00099902 is âthe replacement door latch/lock âassembly used on many â¤Frigidaire dishwashers.It mechanically secures the door⢠during âoperation and contains the electrical â˘switch(s) âŁthat tell the control board â¤the door is closed and/or locked âso a wash cycle can start and â¤runâ safely.
What symptoms indicate the door latch (A00099902)â is âfailing?
Common symptoms are: âdishwasher won’t start and the control indicates the door âis open; intermittent⤠stops midâcycle;⣠the door will⤠not stay latched;â the doorâ lock âŁactuator does not â¤engage onâ highâtemperature⤠or sanitize cycles; or visible physical⢠damage to theâ latch. Sometimes â˘the control âŁwill not accept the door closed signalâ even though the door looks shut.
How can I test the latch electrically before âreplacing it?
After disconnecting power, remove the access needed to reach the latch andâ unplug the latch⣠harness. Use aâ multimeter set⤠to continuity/ohms. With theâ latch in âtheâ “closed” position the door switch â˘contacts âŁshould show⤠continuity (low ohms). âWhen âthe⢠latch is released it âŁshould show open (infinite).If the switch does not change state asâ the latch moves,⣠the â˘switch inside the assembly is âŁfaulty and theâ latch âassembly should be replaced.
Is âthe A00099902 compatible with allâ Frigidaire âmodels?
Not ânecessarily.â A00099902 â¤fits many âŁFrigidaire⢠dishwashers âbut⢠compatibility depends on the exact⣠model and production⣠variation. Verify fit byâ checking âŁyour âdishwasher model number (usually on the tub or door frame) against the part listing on the OEM parts site or⤠retailer. If in doubt, confirm with Frigidaire customer service orâ your partsâ supplier.
What tools âand safety steps are required to⤠replace⢠the latch?
Tools commonly needed: Phillips or Torx⤠screwdriver (model dependent), a âŁmultimeterâ (ifâ testing)and âneedleânose pliers. Safety steps: disconnect powerâ at the breaker or unplugâ the dishwasher before starting; support âtheâ door when removing any screws so it does not⤠fall; avoid stressing âthe door cable âŁor springs.Work⢠slowly and keep track of mounting screws and âany âŁsmall parts.
