B – Heating rod connections:
1.
Each heating rod cable contains four wires. The two larger wires are hot and neutral. The
hot wires from each of the rods are connected to a red butt splice, which has a yellow
wire running to terminal 6 of the relay sockets.
2.
The remaining neutral wire is connected to a blue butt splice, which has a white wire
running to terminal 7 of the relay sockets. This white wire is connected to all heating
rods, all controllers, and all relay sockets through a series of blue butt splices. If one of
these connections is loose, the rods will not heat up.
3.
Make sure these connections are tight.
C – Replacing the relay:
1.
The relays are the clear plastic boxes. First check to make sure each relay is firmly seated
by pushing down gently.
2.
If the relay doesn’t move, continue with replacement. If it does move, firmly seat the
relay, reassemble the unit, and test.
3.
To remove a relay, wiggle it in a circular motion while gently pulling it out of the socket.
4.
Install a new relay by lining up the tab on the plastic post on the bottom of the relay with
the mating part in the socket. Push it firmly into the socket.
