Trane CTR2988 Relay
The Trane CTR2988 Relay is a heavy-duty 24V AC Control Relay, engineered as a direct OEM replacement HVAC part for residential and commercial systems, including Trane and American Standard units. This Double Pole Single Throw (DPST-NO) relay is specifically designed to handle high-amperage induction loads, making it the standard choice for switching power to blower motors, heating elements, and secondary compressors. Unlike generic components, the CTR2988 features a coil optimized for 24VAC signals from thermostats or control boards, preventing the common "chattering" or humming issues that lead to contact welding and premature board failure. With a switching capacity typically rated for 240V, this contactor relay provides the necessary isolation between low-voltage control circuits and high-voltage power components. For field technicians, the compact footprint ensures seamless fitment within cramped furnace control cabinets or outdoor condenser electrical bays. Utilizing genuine Trane replacement parts preserves the original performance specifications and helps maintain system integrity over high-cycle operations.
Key Benefits- Precise 24VAC Switching: Designed specifically for HVAC low-voltage control logic, ensuring clean contact closure without magnetic flutter.
- High Current Load Management: DPST configuration allows simultaneous control of two separate electrical circuits, ideal for complex sequencing.
- Universal Trane Compatibility: Direct replacement for several retired part numbers, ensuring the proper coil resistance and pull-in voltage.
- Industrial Build Quality: Robust contact surfaces are engineered to resist arcing and pitting under heavy inductive motor starting loads.
Can I use a DC relay to replace the CTR2988?
No. The CTR2988 uses a 24V AC coil. Installing a DC-rated relay in an AC control circuit will cause excessive current draw, leading to immediate coil burnout or damage to the transformer.
What are the symptoms of a failing HVAC relay?
Common signs include a visible hum from the control box, intermittently failing blower motors, or pitted contacts that refuse to release, causing components to run continuously.
Is this part compatible with American Standard units?
Yes, as a genuine OEM component, it is fully compatible with both Trane and American Standard equipment that specifies the CTR2988 or CTR02988 part numbers.
