Product Description
The DYNABRADE 1121 is a 12-inch oven thermocouple designed for temperature sensing in commercial cooking equipment. A thermocouple is a two-wire sensing element that generates a small millivolt signal proportional to heat, allowing the oven control system to regulate burner operation. This part is intended for service technicians and commercial kitchen equipment technicians performing thermocouple replacement on gas-fired commercial ovens. The 12-inch probe length suits standard oven cavity installations where the sensing tip must reach the correct position within the heat chamber.
This thermocouple is listed as a replacement for an older part number 2140, indicating it serves as a direct updated replacement in applicable equipment. It is suited for commercial oven applications where IR/CE-rated thermocouples are specified. Technicians servicing commercial cooking lines in restaurants, institutional kitchens, or food service facilities will encounter this style of thermocouple in gas oven pilot and standing-pilot control systems.
Key Features
- 12-inch probe length for standard commercial oven installation depth
- IR/CE designation indicating applicable appliance rating for commercial cooking equipment
- Direct replacement for legacy part number 2140
- Millivolt-output sensing element compatible with standing-pilot gas valve controls
- Designed for accurate temperature signal generation in gas oven environments
Compatibility
Listed as a direct replacement for old part number 2140 in applicable commercial oven applications. Designed as an OEM-style replacement thermocouple for IR/CE-rated commercial gas ovens requiring a 12-inch sensing element.
Installation Notes
Thermocouple replacement on commercial gas cooking equipment should be performed by a qualified commercial kitchen appliance technician or licensed gas technician. Shut off the gas supply and allow the oven to cool completely before beginning any service work. The thermocouple connection at the gas valve is a threaded fitting and should be hand-tightened then snugged with a wrench — do not overtighten. After installation, verify pilot flame engulfs the thermocouple tip properly and confirm the gas valve holds before returning the unit to service.
