Function and Role of⣠the Radiant Module Cartridge in Range Surface āHeating and Control Systems
The A122BA Whirlpool Radiantā Module Cartridge Black serves as the switching ā£and⣠interface element that controls power delivery to⤠a range’s surface heating element. In typical installations āthe cartridge receives a control signal⢠from the ā¢user āselector āor main control board and either mechanically āor electronically interrupts⣠line voltage to the radiant element, producing the⢠stepped āorā modulated heat settings ā£expected by the ā£cooktop. The ā¢module houses the ā¢switching device and mating ā£connector that must match theā appliance harnessand it performs both normal duty switching and aā built-in safety ācutoff to protect the element circuit from āsustained overcurrent or thermal faults.
Technicians should treat the cartridge as a āreplaceable, load-bearing ā¤component: compatibility depends on the cartridge’s pinout, mounting geometryand current/voltage rating rather⢠than cosmetic appearance. Common operational failures include intermittent contact, welded contacts or failed solid-state switches that result in a permanently hot element or āloss of heat ā£output; these faults are diagnosable with ā¢basic measurements (continuity,ā resistance of the ā¢elementand presence of switching at control āsignals). When replacing the cartridge, confirm matching connector and current⣠ratingandā verify proper operation by observing switching action under load and checking for error ācodes or heat irregularities after installation.
- Primary ā£function: ā¢control and⢠interrupt āline power to the surface element.
- Behavior: provides stepped or modulated heat through ā¢contact closure or electronic switching.
- Failure symptoms: no āheat, stuck-on element, erratic heating, visible burning⣠at connector.
- compatibility considerations: pinout, mountingand current/voltage ratings must match the original part.

How the A122BA Whirlpool⣠Radiant Module Cartridge Black Integrates with the Control Board and Element Circuits
The A122BA Whirlpool Radiant Module Cartridge Black functions as āthe interfaceā between the āoven/range control ā¤board and ā£the high-voltage element circuits, translating low-voltage drive commands into a switched ā£mains feed for the radiantā heating elements.⢠The cartridge contains the switching device (solid-stateā switch or relay), drive-input conditioning,ā and basic protection componentsā that allow the control board to command ā£anā element without switching mains current⣠directlyā on the board. In practical use, when⤠the ā£control board outputs a low-voltage call for heat, the⤠module⣠completes the 240 V⤠feed to the element; if the moduleā detects an open circuit⣠or an overcurrent condition itā will typically remain open or presentā a ā£faultā back to⤠the control board depending on theā appliance design.
- Drive interface: low-voltage control signal from the ā¤control board.
- Load switching: āmains-level switching of the radiant⢠element circuit (solid-state or⢠electromechanical).
- Typical behavior: default-open until commanded, provides isolation between control electronics and line⣠voltage.
- Service context: test both the control-drive signal and the module’s switched output when diagnosing element āfailures.
Compatibility concernsā center ā£on pinout,mounting,andā the module’s rated load; ā£theā A122BA⣠Whirlpoolā Radiant Module Cartridge Black must match the⢠control board harness and the element voltage/current⤠rating of the⣠specific Whirlpool ārange model. āTechnicians diagnosing issues should verify the presenceā of the correct low-voltage drive āfrom the control board, confirm proper mains⣠supply to the⣠moduleand check continuity to theā element when theā module is commanded. For example, if the control⢠board sends a drive signal but there is no mains output āfrom the module,ā the cartridgeā is the ā£likely fault; conversely, āif the module supplies mains⢠but⤠the element does not heat,ā the element or its ā¢wiring is at fault.
| Item | Description |
|---|---|
| Connector | Multi-pin OEM harness; must match control⢠board pinout |
| Control signal | Low-voltage drive fromā control āboard ā(logic or PWM depending on model) |
| Load rating | switches mains āvoltage for radiant elements;⢠verify ampere rating against element specifications |
Common⣠Failure Symptoms and Electrical Diagnostic ā¢Indicators of Radiant ā¢Module Cartridge faults
The A122BA Whirlpool Radiant ā£Module Cartridge Black is aā plugāin switching module used ā£on compatible Whirlpoolā electric ā£ranges to control power⣠delivery to a radiant surface element. The cartridge ā¤contains the⤠highāvoltage⣠switching ā¢device and āassociated sensing or timing⣠circuitry that āmodulates the element duty cycle; when the ācartridge fails ā¤you typicallyā see either⤠an open output ā¤(noā heat despite a serviceable element) or⢠a shorted/latched output (element remains continuously powered or trips house āprotection). Replacement must match the original part number and connector/mounting layout to ensure correct signaling and safe handling of line voltageā on the cooktop harness.
- No heat ā£while the element tests āgood – module output open under command.
- Element stays powered or cycles unpredictably – internal switching device fault.
- Intermittent operation that varies with vibration orā temperature – degradedā contacts ā¢or thermal ācomponents.
- Tripped breakers āor blown fuses when the burner is selected – internal short to line ā¤or ground.
- Electrical checks: with⣠power āapplied and the burner commanded ON expect ā¤near line voltage across the module output; with power removed the output should show no⤠short to chassis.
Diagnose by isolating the cooktop and verifying the element āandā harness first:ā ifā an ā¤element shows correct ā£resistance but the module ādoes not present⤠voltage to the element when commanded,the cartridge is āthe likely fault. For live tests measure voltage between the module output terminals with the⢠control commanded ON (typical US ranges use ~240 VAC line-to-line) and verify āno ā¤low-resistance path to chassis ground; for continuity checks remove power and confirm the⢠output is not shorted to ā¤ground. Swapping a known-good module or measuring the presence of line voltage at the module input but not at its output are practical confirmation steps before ā¤replacing the ā¢A122BA Whirlpool radiant āModule Cartridgeā black.
| Item | Description |
|---|---|
| Expected line voltage | ā240 VAC āline-to-line at module input āon āUS ranges |
| Output when commanded ON | Near line voltage present across⣠output terminals; delivers power ā£to element |
| Open-circuit ā¢indicator | Element intact but⣠no voltage at module output |
| Short/ground indicator | Low resistance to⣠chassis or ātripping protectionā when selected |
