Best Broan Bathroom Heater Elements: A Real-World Replacement Guide

Your bathroom heater fan starts blowing cold air in January. The element glows faintly, then nothing. You flip the switch a few times, hoping it’s a fluke, but the room stays chilly and the fan just hums along. A burned-out heating element is one of the most common failures in Broan NuTone heater-fan-light units, and it usually happens years before the motor gives out.

A good replacement element matches your exact model number, uses the right wattage for your circuit, and includes a working thermal fuse. Cheap knockoffs often skip the fuse or use thin wire that burns out in a season. Original Broan parts cost more but fit perfectly. The trick is knowing which trade-off makes sense for your unit and how long you plan to keep it.

Below we break down five replacement elements that fit the popular S97020888 and S97016565 spec, from budget-friendly aftermarket picks to the genuine Broan part. We’ll tell you which one we’d buy, which one to avoid unless you’re in a pinch, and what to check before you order.

Here’s a quick side-by-side of the key specs so you can narrow things down before reading the full reviews.

S97020888 Heater Element Ziyuan

The Ziyuan S97020888 is the element most people land on when they search for a Broan replacement. It’s built for the QTXN100HL, QTXN110HL, 100HL, 110HFL, and 765 series heater-fan-light combos. If your unit blows cold air and the old element shows visible breakage or a blown fuse, this is a direct swap.

What stands out is the iron-chromium alloy wire. It heats fast—the data sheet says up to 200°C—and the thermal limit fuse is soldered inline, so the unit shuts off if things get too hot. The two-pin Molex plug matches the factory connector, which means no wire splicing. For a DIYer with basic tools, the job takes maybe 20 minutes once the housing is down.

The honest downside: this is an aftermarket part, not a Broan factory unit. Fit is usually good, but a small number of buyers report the mounting bracket holes need slight persuasion. Also, the fuse is soldered rather than crimped, which is fine until you need to replace it separately.

• Fits S97020888 and S97016565 applications
• 120V, 1425W-1500W, 60Hz
• Dimensions: 4-1/4 inches long by 2 inches wide
• Two-pin Molex plug, thermal limit fuse inline
• Works with QTXN100HL, QTXN110HL, 100HL, 110HFL, 765HFL and more

Best for: The budget-conscious DIYer replacing a dead element in a common Broan QT or 100-series heater fan.

S97020888 Heater Element FBULWSEC

FBULWSEC’s take on the S97020888 targets the same NuTone model list, but the company leans harder on customer support and testing claims. It’s a solid pick if you want a replacement that ships fast and comes with a support channel that answers within a business day.

The build uses a two-prong Molex plug and an in-line thermal limit fuse, matching OEM spec. FBULWSEC says the part is tested against OEM standards, which is a meaningful claim if true—aftermarket elements often skip the burn-in test. The 120V, 1425W-1500W rating is standard for this class. Installation is the same process: kill power, drop the blower housing, unplug the old element, plug in the new one.

Here’s the catch—availability is listed as scarce, so it may sell out or ship slowly. That’s a real problem when your bathroom is cold and you want a fix this weekend. If it’s in stock when you check, it’s a fine choice. If not, move on.

• Compatible with S97020888 and S97016565 part numbers
• 120V, 1425W-1500W, 50/60Hz
• Two-prong Molex plug
• In-line thermal limit fuse
• Support team responds within one business day

Best for: Buyers who want aftermarket pricing plus a responsive support line, and who can wait if stock is tight.

BroanNutone S97020888 OEM

This is the genuine Broan-NuTone part. No compatibility guessing, no bracket bending, no fuse placement questions. It’s the element Broan ships in the box, sold as a service replacement. If your heater fan is still under warranty or you plan to keep the unit another decade, this is the safe call.

The advantage is fit and finish. Broan’s factory tolerances mean the element drops into the housing exactly like the original. The thermal fuse is positioned where the factory put it, so airflow across the element behaves as designed. That matters more than people realize—an element that runs hotter than intended will trip the fuse early or shorten motor life.

The trade-off is price. Genuine Broan parts typically cost noticeably more than aftermarket equivalents, and the listing here has thin spec details—just dimensions and weight. You won’t find wattage or model compatibility spelled out in the bullet points, so verify your model number against Broan’s parts site before ordering.

• Genuine Broan-NuTone factory replacement
• Exact fit for S97020888 applications
• Dimensions: 1.75 by 1.17 by 0.88 inches
• Weight: 1 pound
• No bracket modification expected

Best for: Owners who want the factory part and don’t mind paying more for guaranteed fit.

S97016565 Heating Element FBULWSEC

FBULWSEC’s second entry swaps the part number focus to S97016565, which is the older cross-reference for the same physical element. It fits QTXN100HL, QTXN110HL, QTXGN100HL, 100HL, 110HFL, and 765HFL models, so most Broan heater-fan-light owners can use it.

The build here is different from the company’s other listing. This one uses a mica insulation layer around the iron-chromium wire, which adds a barrier against electrical leakage. The thermal fuse trips at 110°C—lower than some competitors—which is a good thing in a small bathroom where airflow can be restricted by dust or a clogged grille. Lower trip point means earlier shutdown before damage.

The dimensions listed are 6.7 inches long by 2 inches wide, which is noticeably longer than the 4-1/4 inch spec on the Ziyuan part. That’s a red flag worth checking. Either the measurement includes the mounting frame, or it’s a different form factor. Measure your old element before ordering. If it doesn’t match, return it.

• Fits S97016565 and S97020888 part numbers
• 120V, 1450W-1500W, 50/60Hz
• Mica insulation layer
• Thermal fuse trips at 110°C
• Two-prong Molex plug

Best for: Anyone replacing an element in a dusty or high-use bathroom where overheat protection matters most.

MIYOLO S97016565 Heating Element

MIYOLO’s element covers the widest model list of the five, including QTXN110HFLT, QTX110HFLT, and 100HFL-A. If you’ve got an oddball Broan unit and the other listings don’t explicitly name your model, check this one first.

The mica sheet insulation is the headline feature. Mica resists heat and won’t conduct electricity, so if the wire ever contacts the housing, you’re protected. The 120V, 1425W-1500W rating matches the rest of the field. Installation is the same plug-and-play process as the others.

Where this falls short is documentation. The listing is thin on details—no dimensions, no fuse trip temperature, no installation notes. That’s fine if you already know your model number and just need a part. It’s frustrating if you’re troubleshooting and want to confirm specs before buying. Customer service exists but the response quality is a gamble.

• Fits S97016565 and S97020888
• 120V, 1425W-1500W, 50/60Hz
• Mica sheet insulation
• Covers QTXN110HFLT, QTX110HFLT, 100HFL-A and more
• Plug-and-play Molex connector

Best for: Owners of less common Broan models who need broad compatibility and don’t mind sparse product details.

How We Chose These Products

We started with the two part numbers that come up most often in Broan NuTone heater-fan-light repairs: S97020888 and S97016565. These are cross-compatible in most units, so any element listed under either number had to fit the same model list. From there we filtered out listings with missing wattage, no thermal fuse, or vague compatibility claims.

Fit and safety drove the final ranking. A replacement element that doesn’t seat properly or lacks a working thermal fuse is a fire risk, not a bargain. We weighted OEM fit and fuse quality above price. We also checked whether each listing named specific models rather than saying ‘fits many Broan units’—vague claims usually mean returns.

Buying Guide: What Really Matters

Match the part number first. S97020888 and S97016565 are the same element under different numbers in most cases, but confirm your model appears in the compatibility list. A 120V, 1500W element in a 120V circuit is fine. Putting a 240V element in a 120V unit won’t heat properly, and the reverse can overload the circuit.

Check the thermal fuse. Every legitimate replacement element has one. It’s a small inline component that cuts power if the element overheats. Skip it and you’re relying on the unit’s main limit switch, which may not trip fast enough. If a listing doesn’t mention a fuse, assume it doesn’t have one.

Measure before you order. Element dimensions vary between listings—one here is 4-1/4 inches, another is 6.7 inches. The mounting bracket and housing depth determine what fits. Pull your old element and measure it. If you’re also considering a full unit replacement instead of a part swap, our guide to the best bathroom fan with heater covers standalone options.

Our Top Recommendation

The Ziyuan S97020888 is our top pick. It hits the right balance: correct wattage, working thermal fuse, Molex plug that matches the factory connector, and a price that won’t make you wince. It fits the most common Broan models, and the iron-chromium wire heats fast. The bracket fit isn’t always perfect, but that’s a minor annoyance compared to a part that won’t work at all.

If you want the safest long-term bet and don’t mind spending more, the genuine Broan-NuTone element is the runner-up. It’s the only one here guaranteed to drop in without modification. For a tighter budget, the FBULWSEC S97016565 with its 110°C fuse is a smart pick for dusty bathrooms. If you’re replacing the whole heater rather than just the element, our roundup of the best Broan 178 wall heater is worth a look.

Frequently Asked Questions

Can I use an S97016565 element in place of an S97020888?

Yes, in most cases. Broan superseded the older S97016565 number with S97020888, and the two are physically interchangeable in the models listed above. Verify your specific model appears in the compatibility list before ordering.

How do I know if my heater element is actually bad?

Set a multimeter to resistance and test across the two prongs. A working element shows a few ohms of resistance. An open circuit (infinite resistance) means the wire is broken. Also check the thermal fuse—if it’s blown, the element won’t heat even if the wire is intact.

Do I need to replace the whole heater fan or just the element?

If the fan motor runs and the unit blows air, just the element is usually the fix. If the motor is noisy, seized, or the housing is rusted through, a full unit replacement makes more sense. Our guide to the best electric heater for small bathroom covers alternatives if you decide to replace the whole thing.

What happens if I install an element without a thermal fuse?

You lose the secondary overheat protection. The unit’s main limit switch may still trip, but it’s designed as a backup, not the primary safety. Running an element without a fuse risks melting wiring or damaging the housing if airflow is blocked. Always buy an element with a fuse.
