Rectorseal 33841 Electric Heat Sequencer Replaces W-r 24A34-1

Product Description

The RECTORSEAL 33841 is an electric heat sequencer designed as a direct replacement for the White-Rodgers 24A34-1. Electric heat sequencers stage the activation of resistance heating elements in electric furnaces and air handlers, preventing all elements from energizing simultaneously and protecting the electrical system from excessive inrush current. This staged operation reduces demand spikes and extends the service life of heating elements and associated contactors. The 33841 is a one-for-one replacement unit sold individually, making it a practical choice for HVAC technicians performing maintenance or repair on electric forced-air heating systems.

This sequencer is applicable to residential and light commercial electric forced-air furnaces and air handlers that use staged electric resistance heating. It is typically installed in systems where multiple heating elements must be brought online in sequence to comply with utility load management requirements and to protect branch circuit wiring and breakers. HVAC technicians replacing a failed or intermittent White-Rodgers 24A34-1 sequencer will find the 33841 a direct substitute in those applications.

Key Features

• Direct replacement for the White-Rodgers 24A34-1 electric heat sequencer
• Stages resistance heating element activation to limit inrush current demand
• Sold as individual unit for single-sequencer replacement jobs
• Compatible with standard electric furnace and air handler control circuits

Compatibility

Designed as a direct OEM-style replacement for the White-Rodgers 24A34-1 electric heat sequencer in residential and light commercial electric forced-air heating systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the air handler or electric furnace before removing the failed sequencer or handling any wiring. Refer to the unit wiring diagram located inside the equipment cabinet when making terminal connections. Verify that circuit voltage and load ratings are compatible with the replacement sequencer before restoring power.
