Function âand Role ofâ the 807387501 Frigidaire⣠Dishwasher Timer in Cycle Sequencing
The âŁ807387501 Frigidaire⢠Dishwasher âTimerâ is an â˘electromechanical sequencing⣠device â˘thatâ controls the timing and routing âof power to the wash⤠motor, drain pump, water inlet valve, heaterand dispenser during a cycle. Internally it â˘typically uses a small â˘synchronous âŁmotor driving a cam and contact assembly; as the cam ârotates it closes and opens âspecific âcontacts toâ energize subsystems in theâ correct order and for the correct âdurations. In âmannyâ Frigidaire modelsâ the timer is the primaryâ cycle sequencer, whereasâ in later or âhigher-end models the âŁtimer⣠function âmay âbe integrated⣠into an electronic control board.Proper replacement requires matching the âŁphysical mounting, wiring harness,â contact configurationand rated supply voltage for the dishwasher model to â˘ensure âcompatible sequencing âbehavior.
Failing âtimers⢠moast often present as âa dishwasherâ that â¤willâ notâ advance between â¤fill, wash, drainor dry stagesor that has intermittent⤠operation of the⣠pump, heateror valve. Technicians should⣠inspect the⣠cam lobes and contact faces for pitting or carbon buildup and verify the motor andâ switch continuity against the service âmanual;⢠a worn motor⢠will stop advancingâ while⣠the contacts may still be intact. Practical examples include a unit that completes fill but never starts the wash motor (stuck contacts)or âone that drains but does not advance to the dry cycle (broken cam or motor).Replacement guidance: confirm the 807387501 âFrigidaire dishwasher Timer âmatches the model number and connector âpinout on â¤the⤠machine,⣠and consider that swapping a mechanicalâ timer into a machine designed for an electronic control board will not restore proper operation.
- Common symptoms: âstuck in â¤wash or fill,⤠no drain,⢠no⢠heat during dry, intermittent cycle advancement.
- Primary failure âŁmodes: worn contact surfaces, seized or weak timer motor, broken cam⤠or mounting âtab.
- Compatibility checks: verify part number,connector pinout,mounting â¤points,andâ nominal supply⣠voltage beforeâ replacement.

How âthe âŁ807387501 Frigidaire dishwasher Timerâ Interfacesâ with Motors, Solenoidsand Control⢠Circuits
The 807387501 Frigidaire Dishwasher Timer âis an electromechanical timing unit that sequences mains â¤power⤠to âthe âdishwasher’s motors, solenoidsand auxiliary control inputs through cam-actuatedâ switch â¤banks⢠or â˘relay outputs. During eachâ cycle the timer closes âŁspecific contacts to supply the wash/circulation motor, theâ drainâ pumpand the âŁwater inlet solenoid in the correct order; it alsoâ provides âpower â˘to the timer driveâ motor andâ interfaces with â˘interlocks suchâ as the door â¤latch and float sensor so those devices can interrupt â˘or permit âpower flow. Replacement compatibility depends âŁon matching the terminal layout, switch functionsand⢠voltage rating âŁto the original unit – a timer â¤with â˘the same connector pattern and contact assignments âwill âengage the same⤠motors and âŁsolenoids âwithout rewiring the harness.For⢠example, in the wash segment the timer â¤will route â¤mains to â¤the circulation motor and to any âassociated ârelays, while in the âŁdrain segment it switches âthe drain pump output and disables the inlet solenoid to prevent refilling.
- Typicalâ outputs: wash/circulation motor, drain pump, inlet solenoid, âtimer motor/clock and line/common inputs.
- Compatibilityâ checks: terminal labeling, âcontact function⣠(normally open/closed), harnessâ connector orientationand⢠rated⤠voltage/current capacity.
- Diagnostic cues: â¤a stuck⣠or burned timer contact may â˘power a solenoid butâ fail to âŁstart the motor, indicating contact wear rather⢠than a motor fault.
| Item | Description |
|---|---|
| Motor output | Provides mains to circulation/drainâ motor â˘during wash orâ drain intervals |
| Solenoid⣠output | Supplies the water â¤inlet â¤or⤠dispenser solenoid during fill or dispense steps |
| Timer drive | Low-current supplyâ for âthe â˘timer’s internal clock or synchronous motor |
| Line/Common | Main supply and return conductors distributed⤠through cam⣠switches |
Technicians âverify correctâ interface behavior by⢠observing expected voltages at⢠the timer’sâ outputâ terminals while advancing the⢠timer or running a â˘diagnostic cycle:⤠useâ a multimeter to confirm⣠the presence of mains at the motor⢠or solenoid terminal when that function should be activeand check continuity across the timer’s camâ switches⣠when they are engaged. If âa solenoidâ energizes but the motor⣠does not receiveâ voltage, the timer contact for the motor isâ the likely fault;⣠conversely, intermittent motor operation âwith stable⤠voltage suggests â˘the motor or⢠its⤠wiring. Always isolate âŁpower before performing continuity checks and ârespect âthat âthese outputs switch household â¤mainsâ – many⤠failures are visible as pitting or âdiscoloration on âcontactâ surfaces,⢠and⣠correct âreplacement involves matching the â¤physical terminal âŁmap and current ratings rather than only â˘matching the enclosure style.
Common Failure⤠Symptoms and Diagnostic⤠Tests âfor Timer-Related Faults
The â˘807387501 Frigidaire Dishwasher Timer is â¤an⤠electromechanical sequencer thatâ routes⤠lineâ voltage to âthe pump, heater, inlet valve âand motor at the âŁcorrect â˘points in a wash cycle. Faultsâ in this timer typically manifest as failure⣠to advance between cycle âsteps, â¤intermittent â¤or no power to âother âcomponents,â unusual clicking or humming from the control area,⢠or burnt/charred â¤terminals visible at the connector block. As â˘the âtimerâ both contains a â¤small synchronous âŁmotor and âmultiple cam-operated contact sets, replacements must match the â¤original part âŁnumber andâ terminal âlayout to maintain correct switching order and compatibilityâ with the⤠machine’s wiringâ harness â¤and control logic.
- dishwasher fills but â˘does â˘not⣠drain âŁor advance to wash – stuck or failed advance contact.
- Noâ motor/pump/heater power while other parts⢠(likeâ the âinlet valve) âfunction – âselective contact failure.
- intermittent operation or random skips between steps – worn cam contacts or intermittent âcontinuity.
- Audible hum without rotation – seized timer⤠motor or stripped gears.
- Visible⣠burning or pitting on terminals – overheated⢠switch contacts needing replacement.
diagnostic tests combine safe live-voltageâ checksâ and low-voltage âcontinuity measurements. With power off, verify â˘continuity through⢠the⢠timer motor and âŁacross each cam-operatedâ contact â¤using a multimeter; âŁan⤠openâ circuit in the motor winding or a contact that fails to⢠close when⤠the timer is manually advanced indicates â˘internal failure. â˘With⤠power restored and a helper selecting⣠aâ cycle, confirm 120V (or the appliance supply⤠voltage) is present at the timer’s incoming supply terminals and that â˘voltage â˘is switched outâ to âthe appropriate loadâ terminals when the timer steps; lack of switching under live conditions pointsâ to burned contacts or a seized â¤mechanism. Practical âexamples: âŁif the washer pumps but the timer never⤠advances, measure the motor âŁwinding for continuity and manually rotate the shaft to see if contacts âmake; if the motor âhums but doesn’t turn, inspectâ gears and âthe motorâ shaft for mechanical seizure. Always disconnect mains âbefore continuity checks and exercise caution when measuring âlive⢠voltages; replace the 807387501 âFrigidaire Dishwasher Timer if internal â˘contacts are damaged or âthe âmotor winding is open or âshorted.
| Item | Description |
|---|---|
| Continuity of⤠timer motor | Low resistance expected; open â¤=â failed motor â¤winding |
| Contact âswitching | Cam should close specific circuitsâ when⣠advanced; intermittent = worn contacts |
