Jenn-Air CVEX4370B cooktop Parts

The “best” electric cooktop brand depends on what you value most (reliability, features, serviceability, or price). For a premium built-in electric downdraft cooktop like Jenn-Air model CVEX4370B, Jenn-Air is a strong choice when you want integrated ventilation and a higher-end fit and finish; use the CVEX4370B installation guide to confirm electrical and cabinet requirements before you buy or replace anything.

How we recommend choosing the best brand

We see customers happiest when they pick a brand that matches their cooking style and installation constraints.

• Induction vs. radiant electric: induction is typically faster and more efficient; radiant is simpler and often less expensive.
• Ventilation needs: downdraft models (like many Jenn-Air setups) can be the deciding factor if you cannot vent a hood.
• Controls and usability: look for clear knob or touch controls, hot-surface indicators, and easy-to-clean surfaces.
• Parts availability: brands with readily available knobs, filters, and electrical parts are easier to maintain.
• Electrical requirements: verify circuit size and wiring method before selecting a model.

Brand comparison (quick guide)

What you want most	Best fit (typical)	What to watch for
Fast heating, efficiency	Induction-focused lines (varies by brand)	Cookware compatibility, higher upfront cost
Easy everyday cooking, broad options	Mainstream brands with wide model ranges	Fewer premium features on entry models
Premium design and built-in downdraft	Jenn-Air and similar premium lines	More complex installation and venting layout

Why installation details matter (especially for downdraft cooktops)

For electric downdraft cooktops, the installation can be as important as the brand. The CVEX4370B installation instructions call out key electrical items such as proper grounding and using the correct wire gauge and circuit sizing for the cooktop width. Confirming these details upfront helps prevent nuisance power issues and avoids rework.

Parts and upkeep that affect long-term satisfaction

Even the best brand performs poorly with restricted airflow or worn controls. For CVEX4370B, common maintenance and replacement items include the downdraft filter and fan-related components.

• Replace a clogged vent filter with the filter WPY706012
• If the vent fan gets noisy or vibrates, inspect the blower wheel WPY707985
• If a control knob is cracked or slipping, check the range burner control knob WP706035

Replacing the “stove top” on a Jenn-Air CVEX4370B electric cooktop typically runs $300 to $1,100 total: about $200 to $800 for the cooktop or major top assembly plus $100 to $300 for installation labor. Downdraft models can land on the higher end because venting and electrical work are more involved.

What drives the price up or down

• Type of top: coil is usually least expensive; smooth glass and induction cost more.
• Downdraft ventilation: ducting, clearances, and blower access add time.
• Electrical requirements: this cooktop uses a dedicated 120/240V, 60 Hz supply and circuit sizing varies by cooktop width (20-inch, 30-inch, 45-inch). Confirm details in the installation guide.
• Countertop work: modifying the cutout or reinforcing cabinetry increases labor.
• What you are actually replacing: sometimes you only need a control, knob, or vent part instead of the entire cooktop.

Repair vs. replace: quick cost comparison

Option	Typical parts cost	Typical labor	Best when
Replace a small part (knob, filter, terminal block)	$10 to $150	$0 to $200	One function failed but the cooktop is otherwise solid
Replace downdraft components (blower wheel, filter)	$40 to $150	$100 to $300	Vent fan is noisy, weak, or not moving air
Replace the full cooktop/top assembly	$200 to $800+	$100 to $300+	Multiple burners or controls are failing, or the top is damaged

Parts that commonly solve “stove top” problems on this model

If your goal is to restore performance without replacing the whole cooktop, these CVEX4370B parts are common fixes:

• Filter WPY706012 (restricted airflow, greasy odors)
• Blower wheel WPY707985 (loud vent fan, vibration, weak airflow)
• Terminal block WPY708730 (burning smell at wiring connection, intermittent power)

Why it matters

This is an electric downdraft cooktop, so replacement cost is not just the glass or burners. Venting rules (for example, using the correct metal duct size and keeping duct runs appropriate) and safe electrical connection planning can significantly affect labor time and total cost.

Most Jenn-Air electric cooktops, including model CVEX4370B, last 10 to 15 years with normal household use. Keeping the glass surface clean, protecting the controls, and maintaining the downdraft ventilation system helps you reach the full lifespan.

Typical lifespan and what affects it

A cooktop’s life is mainly determined by heat exposure, electrical connections, and how well the surface and ventilation stay clean.

• Daily heat load: frequent high-heat cooking shortens element and control life
• Spills and boilovers: can damage switches and seep into the control area
• Ventilation upkeep: clogged filters make the blower work harder and run hotter
• Electrical quality: loose or overheated connections can cause intermittent power loss
• Cleaning habits: abrasive cleaners can permanently damage glass and markings

Maintenance that extends the life of CVEX4370B

Use these habits to reduce wear on radiant elements, knobs, and the downdraft blower.

• Clean the cooktop after it cools; remove sugary spills as soon as safely possible
• Keep the downdraft filter clean and seated correctly; replace it when it no longer cleans up well
• Avoid sliding rough-bottom cookware across the glass
• Do not block the vent intake while cooking
• If the vent fan gets noisy or airflow drops, inspect the filter and blower area

What you notice	Most common cause	What we recommend
Vent fan loud or vibrating	Grease buildup, worn blower wheel	Clean the filter; inspect/replace the blower wheel WPY707985
Weak downdraft airflow	Clogged filter, duct restriction	Clean/replace the filter WPY706012; confirm ducting is clear
Cooktop intermittently loses power	Loose/burned wiring connection	Have the electrical connection checked; replace the terminal block WPY708730 if damaged

Why it matters

A cooktop that is kept clean and properly vented runs cooler and draws steadier electrical current. That reduces stress on the heating elements, control components, and downdraft blower, which are the parts that most often limit overall service life.

For model-specific use, care, and cleaning guidance, follow the CVEX4370B installation guide. For replacement parts and diagrams for this model, shop the parts list on this page or search by model number on Sears PartsDirect.

Most electric cooktops cost about $200 to $1,000, with price driven mainly by size, heating technology (radiant vs induction), and features like downdraft ventilation. For your Jenn-Air CVEX4370B downdraft cooktop, installation requirements can also affect total cost; see the installation guide.

What changes the price the most

• Size and cutout: 20-inch, 30-inch, and 45-inch models typically step up in price as they get larger.
• Heating type: radiant electric is usually less expensive than induction.
• Downdraft ventilation: built-in venting adds cost versus a standard electric cooktop.
• Controls and design: touch controls, specialty zones, and premium glass finishes raise price.
• Electrical and venting needs: a dedicated circuit and proper ducting can add installation labor and materials.

Typical cost ranges (cooktop only)

Type of cooktop	Typical price range	Notes
Basic radiant electric	$200 to $500	Simple controls, fewer features
Mid-range radiant electric	$500 to $900	More power levels, better glass, larger sizes
Induction cooktop	$700 to $2,500+	Faster response, needs induction-ready cookware
Electric downdraft cooktop	$900 to $3,000+	Vent system and blower add complexity

Installation costs to plan for (especially on downdraft models)

For Jenn-Air downdraft cooktops like CVEX4370B, the install can add meaningful cost because it often involves both electrical and ductwork.

• Dedicated electrical circuit: these cooktops use a 120/240V supply on a dedicated circuit (amperage varies by size).
• Junction box connection: the cooktop typically connects to a junction box through flexible metal conduit.
• Venting materials: common venting uses 6-inch round or 3-1/4 inch x 10 inch rectangular metal duct; shorter straight runs may allow 5-inch round in specific cases.
• Cabinet modifications: clearances and routing for the blower and grease container can require carpentry.

Why it matters

A cooktop’s sticker price is only part of the budget. With a downdraft electric cooktop, the electrical circuit, ducting path, and cabinet clearances often determine whether the total project stays affordable.
