We'll continue our systematic method of figuring out a swimming pool heater by searching at how to proceed once the light within the control pad on top of your Sta-Rite pool and health spa heater that's labeled "service heater" is lit. (We'll proceed using the assumption you know from segment one.) This time around you will have to take away the sides in the heater before disconnecting energy towards the heater to ensure that read the codes around the board connected to the topside. After getting rid of the edges, you will notice the large topside that's still attached to the heater. Underneath the topside is really a metal panel that keeps the topside in position. Under this panel you will find two securing hooks (cotter hooks). Carefully take away the two hooks and store them somewhere safe until reassembly. Lightly take away the top and switch it upside lower. You will notice an easy lit around the board you're searching at whenever you turn the topside over. The sunshine is going to be alongside a code that's written around the board.
The very first code that you will see around the left side from the board is going to be PS. This is actually the code for that pressure switch. We covered pressure switch in segment one. If the light is lit return to segment one and review that segment. If required do as instructed to exchange pressure switch.
The following code you will see around the board is HLS. For those who have a controller around the system you will have to bypass it at this time around. You will have to carefully disconnect the energy in the heater. Once you are certain the energy is disconnected, you will have to find and open our prime-current cabinet. This cabinet is really a metal box in the center of the heater. If you're searching in the cabinet, there's often a screw on top right side. Release the screw and also the door will swing lower toward you. You have to be very careful when employed in this box and just achieve this when you're certain the energy towards the heater is OFF.
You will have to bypass the firewall safety interface. To get this done you may need a short wire with stab-tab fittings. For those who have a controller also it was correctly installed the wire might have been left within the box through the tech who installed the controller. Otherwise you will have to get this to jumper wire. At this time try looking in your user guide to discover the 2 proper hooks for connecting to. For those who have a controller or are utilizing a fireman's switch this is when your control ought to be connected. For those who have a controller which is not connected here, it might cause your problems and only possess a licensed tech correct the issue or correct it yourself.
You have to take care not to place the jumper wire around the energy devices or else you will destroy your heater by using up the electronic system. Make use of your manual to discover in which the fireman's switch should be attached and thoroughly attach your jumper between these devices. Should you now switch on the energy and also the heater works with no problems, your condition is based on the controller or even the wiring visiting the controller. You will have to trouble shoot this technique.
If you've still got exactly the same trouble with your heater. ("service heater" light occurs), leave the jumper in position and verify the pump is on which you've good waterflow and drainage. Make certain again together with your meter the pressure switch isn't cycling. It ought to read like a dead short. (See segment one) With higher waterflow and drainage verified and also the "service heater" light on, your condition might be among the thermo-government bodies within the safety system.
Since we began this using the indicator light around the board lit alongside HLS, the very first factor we will check would be the wires visiting the high limit switch. Our prime limit switch is situated close to the bottom around the left side from the water manifold while you face the facts. To determine it you have to take away the side cover around the water manifold. The screw store the cover is on top of it. You have to make certain the orange wires visiting the switch are intact, attached and never corroded. When the wiring is nice, make use of your multi-meter to check on the high limit switch reads like a dead short. Whether it reads open and also the water isn't above 104 F, switch the high limit switch. If this doesn't fix your condition you might have a poor control board also it will have to be changed. Testing the control board is an extremely involved process and will also be worked within a later segment.
This is actually the finish of segment two and it has taken you thru area of the safety circuit within the heater and a pair of from the indicator lights around the board. We'll move on with our systematic identify of problems around the Sta-Rite pool and health spa heater within the next segment.
