Watkins Iq 2020 Heater Relay Board W/ Jumpers Pn 74618 2001-2009 New Pn 77119

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 Model Years: 2001-2009 Replaces Watkins Old Part Number: 74618 & 73355(New as of 9-10-2013) This IQ2020 Heater Relay Circuit Board is the newest revision for the 2001-2009.5 IQ2020 Control Box. 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. This upgraded circuit board replaces the 1st, 2nd, or 3rd generation boards in the IQ2020 Control Box found in all 2001-2009.5 Hot Spring, 2001-2009 Tiger River and 2008-2009 Limelight spa models. Symptoms this part has failed: • No power going to the heater even though the red HTR ON L.E.D. Light is lit inside the IQ2020 control box.
