Stove fan Peltier replacement

Updated: October 2026

The wood-burner fan on the stove top has slowed to a twitch or stopped, and the only part that looks replaceable is a small square under the base. A stove fan Peltier replacement is often a generator module, not the 60 W cooler that amazon.co.uk shows first. You should leave this page knowing whether to try the maker's spare, what a generic 40 mm tile is risking, and when the motor is the more likely failure. Prices in the comparison are amazon.co.uk shelf figures. Maker spares below are shop pages, not ASINs in that table. The full rows are the [Peltier element comparison](/hub/electrical-equipment/peltier-element). We did not strip a fan on a stove.

Fan stopped: module or motor

Caframo's Ecofan FAQ splits the two parts in a way that is useful even if your fan is another brand. The motor is often the piece that lasts a few seasons. The thermoelectric module usually lasts longer, unless the fan was dropped or the base was overheated. If the blades are free and the fan is simply silent, you still do not know which half died. Caframo's check is a small battery, on the order of 9 V, at the motor leads. That only tells you the motor can turn. A 40 mm footprint is not proof the tile is the right spare. Heat-powered fans use a TEG. Many TEC1-12706 listings are powered coolers. Reviewers do put those coolers into wood-burner fans. That shows the square sometimes fits. If a 9 V check does not spin the motor, a new module will sit on a dead motor. Caframo does not sell a replacement module for Ecofan.

TEG spare versus a TEC1-12706

A TEG wants a temperature difference and a heatsink on the cold face. A TEC wants a DC supply and a hot-side sink. The only generator listing in our comparison is the Youmile SP1848-27145 pair, B091YNXSKM, at about £8.99, 3.6 from 35 reviews, 40 × 40 mm, with 150°C in the title and no Qcmax. The same title also calls it a cooler. The sheet quotes about 4.8 V open circuit at a 100°C difference. That is a small fan voltage, not a refrigeration wattage. Cosystove's replacement generator was £16.99, with a connector for their fans. Valiant's replacement for named premium fans was also £16.99, with paste already on the faces. Either is the fair first buy when the fan brand matches the shop. A TEC1-12706 is the alternative when no maker spare exists and you are willing to gamble. UK reviews on that class are repairs people attempted. They are not a fitment drawing. A TEC range of −30°C to 70°C is not the stove-top temperature.

What the amazon.co.uk reviews show

On the diymore five-pack, one reviewer replaced the element in a wood-burner fan. On the about £7.99 pair, notes include a stove-fan spare, a cracked tile on arrival, and a log-burner spare that failed after a few weeks. The SP1848 pair is the listing that is actually a generator. One set repaired a stove fan. Other notes are tiles that arrived dead, and one repair that lasted about eight weeks. Paste does not turn a TEC into a TEG.

When not to open the fan

Leave the fan closed when the base was run far hotter than the maker allows, or when the unit was dropped. Caframo treats those two events as the way a module dies early. Leave it closed when you cannot name the brand and no spare drawing exists. A 40 mm square is shared by coolers, generators, and two-stage tiles. Flue, clearances, and the carbon-monoxide alarm belong with a stove professional. If the fan housing is melted, a module swap will not make it safe. When a maker spare exists and the brand matches, buy that spare first. The generic tile is the path only after the motor still turns.

Common questions

Is the module or the motor dead?
You cannot tell from a silent fan alone. Caframo's check is a small battery, about 9 V, on the motor leads. If the motor does not spin, accept that fault before you buy a tile. If it spins and the fan stays still on a hot stove, the module or the thermal joint is the suspect.
Should I buy a TEC1-12706 or a TEG?
Buy a TEG when the fan is heat-powered and the maker sells one. Cosystove and Valiant listed theirs at £16.99. Buy a TEC1-12706 only as a gamble when no maker spare exists. The Youmile SP1848 pair is the TEG in our table, with a title that also says cooler.
Can I get an Ecofan module?
Caframo's FAQ says they do not sell the thermoelectric module. A marketplace 40 mm plate is not an official Ecofan spare. Their stove-top bands, which reach about 345°C on some models, are not the rating printed on a TEC that says −30°C to 70°C.
What temperature is too hot for the tile?
Follow the fan maker's base-temperature limit, not the hottest stove in the Ecofan table. A TEC1-12706 range of −30°C to 70°C is a poor match for a hotter stove top. The SP1848 title prints 150°C, and the sheet says not to exceed the stated maximum.
Why did a replacement last only weeks?
The captured SP1848 notes include a repair that lasted about eight weeks, plus tiles that arrived dead. The about £7.99 pair includes a log-burner spare that failed after a few weeks. Causes in the maker FAQ are overheating and impact. Prefer the £16.99 maker spare when it exists.
Is a generic tile cheaper than a new fan, and when is that a false saving?
A generic pair at about £5.99 to £8.99 is less than the £16.99 maker modules. It is a false saving when the motor is the failed part, when the first pair arrives dead, or when you buy a TEC for a fan that needs a TEG and then buy again.
