Watkins IQ 2020 Heater Relay Board with Jumpers PN 77119 (NEW) PN 74618 (OLD)


Watkins Hot Spring & Tiger River Heater Relay Board w/ Jumpers PN 77119 (old PN 74618 & 73355). Replaces Watkins Part Number: 74618 as of 09/10/2013. Replaces Watkins Old Part Number: 74618 & 73355. It’s upgraded design provides a more efficient method of connecting the heater’s power cord to this board therefore reducing fatigue on the two “beefed up”relays. 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 its own separate gray terminal block labeled H2. This will reduce stress on the relays and increase their lifespan due to better transfer of voltage. The ground wire connection remains the same. The incoming power wires and the black & white wire from the heater are inserted into the gray terminal blocks round holes by prying the gate open using a small screwdriver. Symptoms this part has failed: No power going to the heater even though the red HTR ON L. Light is lit inside the IQ2020 control box. The heater board is charred on the front and/or the backside.
