Disconnect power, unscrew and open upper access panels to access the heater kit from the unit. 2. Locate the TCO(s) and disconnect the 2 black wires per TCO. Using a multimeter, measure continuity/ resistance of the fuse element by placing the test probes across the two terminals to verify if the fuse has failed. The quantity of TCO's depends on the heater kit model. The heater kit model shown in Figure 2 has two TCOs. 3. Unscrew the defective TCO from the base plate and using the same screw(s) mount the new one back in the same spot. 4. Re-connect all the wirings in the same terminals that you disconnect it from. 5. Mount the access panel back in the unit. 373 Atascocita Rd., Humble, TX 77396 · Phone: 281.441.6500 · Toll Free: 800.423.9007 ·Fax: 282.441.6510 www.aspenmfg.com Subject to change without notice and without incurring obligation. © Copyright 2024 Aspen Manufacturing.
