Caldera Spa Replacement Heater Relay Board 77119 with Jumpers and Shortened Screws for The Front Cover.

This Is The Newest Revision For The 2001-2008/Early 2009 IQ2020 Control Box.

This part found in Caldera, Hot Springs,Tiger River, And Lime Light Spas.

NOTE FOR WIRING: The Black Wire From The Heater's Power Cord Now Connects Into The H1 Position On The Large Gray Terminal Block. The Heater's White Wire (Neutral) Connects Onto It's Own Separate Gray Terminal Block. This Will Reduce Stress On The Relays And Increase Their Lifespan Due To Better Transfer Of Voltage. The Ground Wire Connection Remains The Same. There Is A Voltage Jumper In The Upper Left Corner That Is Factory Set; Although there is a Reference To Instructions, NO Field Action Is Required Relative To This Jumper At This Time (It Is For Potential Future Use). This Board Replaces Part Number 74618.

SYMPTOMS OF PART FAILURE: No Power Going To The Heater Even Though The Red HTR ON L.E.D. Light Is Lit Inside The IQ2020 Control Box. The Heater Board Is charred On The Front And/Or The Backside.
