Parts under review / AC Contactor
AC Contactor
- A
- Body width on the DIN rail
- 230V~
- Coil voltage, printed on the side
Coil voltage is the usual ordering error — people match the current rating and overlook it, and the contactor will not pull in at all. Photograph the printed side. The current rating must exceed the element load on that circuit, with margin.

Reference photo
Switching contactor for the heating circuit. A common cause of a deck that has gone completely cold.
Useful first checks. If the contactor clicks when the oven calls for heat and the elements still stay cold, the contactor is doing its job — look at the elements.
What this part is
An electrically operated switch. A low-current coil, energised by the thermostat or controller, pulls in heavy contacts that carry the element load. It exists so a delicate control device never has to switch tens of amps.
How it fails
Contacts erode and weld, or the coil opens. A welded contactor is the dangerous one: the oven heats continuously regardless of the thermostat, and the first sign is burnt product rather than a fault code. A failed coil is benign by comparison — the oven simply stays cold and silent.
What decides whether a replacement fits
These are category-level selection factors, not specifications for a specific product. Confirm each value from the machine and the physical part.
| Parameter | Typical | Why it matters |
|---|---|---|
| Coil voltage | Read the coil voltage and AC/DC marking on the installed contactor. | The most common ordering error on this part. It is printed on the side of the contactor — photograph it. |
| Current rating | Rated in amps AC-1 or AC-3 | Must exceed the total element load on that circuit, with margin. An under-rated contactor welds. |
| Pole count | 2, 3 or 4 pole | Has to match how the elements are grouped in your machine. |
| Mounting and body width | DIN rail, in standard modular widths | The control panel has a fixed amount of rail. A physically larger replacement may not fit beside what is already there. |
The mistake people actually make. Matching the current rating and overlooking the coil voltage, which leaves you with a contactor that will not pull in at all.

Fits these models
We have not published a verified model list for this part yet. We only list a machine once we have measured the part against it or a customer has confirmed the install — a list padded with guesses is worth less than no list.
Send us your nameplate and a photo of the old part and we will review what the evidence supports.
What to photograph and measure
The coil voltage is printed on the side of the contactor — photograph it. Getting this wrong is the single most common ordering mistake on this part.
