2-Pack Baseboard Heater Thermostat Dial Knobs — White Replacement
Product description
Package and contents: The package includes two white baseboard heater thermostat replacement knobs. Package dimensions are approximately 4.3" x 2.95" x 0.5" and the total pack weight is about 0.03 lb.
Knob dimensions and design: Each knob has an outer diameter of 2 inches. The D-shaped recess that fits the control stem measures roughly 1/4" long by 5/32" wide. The knobs are molded with ribbed sides to improve grip when making adjustments. The front cap is printed with temperature positions labeled OFF, LO, MED and HI for easy reference.
Compatibility and fit: These dials are intended for the left or right front positions on compatible units where the half-moon stem is used. They are compatible with engineered product lines such as the 1800, 1900, 2500, 2600, C1800 and C2500 Series Model C baseboard heaters and the F2500 Series. They also fit many older electric baseboard and wall heater models from manufacturers like Fahrenheat, Dayton, Qmark, Berko and Leading Edge, and are suitable replacements for Cadet F Series controls and accessory kits including FTA1A, FTA2A, TA1ANW, TA2ANW, TA1ANWCA and TA2ANWCA.
Where to use and installation: Common rooms for use include bedrooms, living rooms, kitchens, bathrooms, basements, offices, hallways and attics. Installation is straightforward — the knob slides onto the control stem without tools and secures by the D-profile. They are intended to restore tactile temperature selection on older units that use the half-moon style stem.
Pros
- Includes two knobs; simple slide-on installation
- Clear OFF/LO/MED/HI markings and ribbed grip
- Compatible with many older baseboard models
Cons
- Fits only specific half-moon stem profiles
- Limited color option (white only)
- Not adjustable for non-D-shaped stems
VerdictHandy, practical replacements that restore control to older electric baseboard units. They match the half-moon stem profile used on many vintage and Cadet F-style heaters, offer a secure ribbed grip and clear OFF/LO/MED/HI markings, and install easily by sliding onto the control shaft.

Good for rental maintenance
Arrived in good shape. I replace knobs in my vacation rental because guests can be rough; these look sturdy and should hold up fine.

Handy replacements
When my original knob broke I used pliers and even tried glue, but neither was satisfactory. I used an image search to identify a match, ordered replacements, and they fit the control stem and let me adjust the heat without tools. Very useful.

Perfect fit for vintage units
In a 1950s house with original baseboard heaters, many units lacked knobs. These were the right size, easy to install and feel well made — operating smoothly since installation.

Exactly what we needed — curious it's the only match
Several heating controls in our older house had been missing for years; these restored function instantly and made the rooms usable again. I’m baffled that this was the only replacement that matched the half-moon shaft, but the knobs themselves work perfectly.
