Carrier 08-2833-68 Limit Switch
The Carrier 08-2833-68 Limit Switch is a critical safety component designed for high-performance thermal regulation in HVAC systems, specifically within gas furnaces and electric heat kits. This L135-45F limit switch functions as a primary high-limit safety, engineered to open the electrical circuit when internal plenum temperatures reach 135°F and automatically reset once the temperature drops to 45°F. For veteran technicians, this OEM part is essential for resolving Carrier error code 33 or code 13 lockout conditions, which typically indicate restricted airflow or excessive heat exchanger temperatures. Built with a durable snap-action disc mechanism, it ensures precise position sensing and reliable contact operation in demanding environments. This HVAC safety limit is compatible with various Carrier and Bryant models, including EHK3 and FMC4Z series heat kits. Utilizing genuine OEM furnace parts like the 08-2833-68 ensures exact factory specifications are met, maintaining the system's intended sequence of operation and protecting the heat exchanger from thermal stress.
Key Benefits- Precise Thermal Calibration: Fixed 135°F trip point prevents heat exchanger damage without frequent nuisance tripping.
- OEM Compatibility: Exact drop-in replacement for Carrier 08-2833-68, ensuring proper terminal spacing and mounting alignment.
- Automatic Reset: Resets at 45°F, allowing for system recovery once airflow issues are cleared.
- Increased System Safety: Provides a redundant mechanical fail-safe against blower motor failure or clogged evaporator coils.
- What causes this switch to trip repeatedly? Frequent tripping is often caused by restricted airflow due to a dirty secondary heat exchanger, high-MERV filters, or failed blower capacitors.
- How do I test the 08-2833-68? After the furnace has cooled, check for continuity across the terminals. If the circuit remains open at room temperature, the switch is defective.
- Can this be used in electric heat kits? Yes, this specific switch is found in many EHK series electric heater assemblies to monitor element temperatures.
