R68AB0008  Mortex HEAT RELAY SP  

Mortex R68AB0008 OEM SP Heat Relay The R68AB0008 is the factory single‑pole heat relay used in Mortex air handlers and electric furnace systems. This 24‑volt relay energizes the heating circuit and ensures proper activation of heat strips during heating operation.

When older relays stick, chatter, or fail to close under load, the R68AB0008 restores correct heat‑strip performance and prevents intermittent or no‑heat conditions. Designed for manufactured‑housing HVAC systems, it installs directly into Mortex control housings with OEM fitment.
