check gas pressure if too low it soots up and overheats

The fuse link is a device that will open when over heated. If the exhaust temp is to high it will open and is a one time device. It can not be reset it must be replaced with a high temp fuse link made for the exhaust location. It will have a red mark on it indicating high temp. Low gas pressure can cause a lean fuel condition that may cause the exhaust temp to rise enough to trip the link. I would also check for scale inside the heat exchanger. Scale inside the heat exchanger will not allow for proper heat transfer to the water, this will cause excess heat to be present in the exhaust. Proper water balance and flow are very important.

If you have checked the circuit breakers and they appear to be functioning properly, here are a few other things you can try:

1. Check the GFCI outlet: If the AquaLink RS is plugged into a GFCI (ground fault circuit interrupter) outlet, make sure the outlet hasn't tripped. You can do this by pressing the "reset" button on the outlet.
2. Check the transformer: The AquaLink RS requires 24 volts AC power to operate. If the transformer that converts your home's AC power to the 24 volts required by the AquaLink RS is faulty, it can cause the system to fail. Use a multimeter to test the transformer to ensure it's supplying the proper voltage.
3. Check the power supply: If the transformer is supplying the proper voltage but the AquaLink RS is still not receiving power, the power supply board may be faulty. Check the power supply board for any obvious signs of damage, such as bulging or leaking capacitors.
4. Check the wiring: It's possible that a wire has become loose or disconnected, preventing the AquaLink RS from receiving power. Check all of the wiring connections to make sure they're secure and tight.

If you're still unable to get power to the AquaLink RS, it may be time to call a professional pool technician to diagnose and repair the issue.

1. Check the air sensor: The first step is to locate the air sensor and check for any visible issues. Make sure it is properly connected and not damaged.
2. Check the wiring: If the air sensor appears to be in good condition, the problem may be with the wiring. Check the wiring for any loose connections or damaged wires. If you find any issues, you may need to repair or replace the wiring.
3. Check the control board: The control board is responsible for managing the various functions of the pool heater. If the control board is malfunctioning, it can cause the air sensor to short out. You can check the control board by testing it with a multimeter. If you suspect the control board is the problem, you may need to replace it.
4. Check the air intake: If the air intake is blocked or restricted, it can cause the air sensor to short out. Make sure the air intake is clear and unobstructed.

go into system set up and turn on on remote

see if hooked up with 4 wire from heater to aqualink if so try checking wires for one loose or off if ok try to use the firemans swith to pins 1 and 2 then heater button will work

bad display board

replace water sensor that goes from board to header

check the air switch hose make sure not pinched or hole in it then if ok make sure fan running correct speed

check with your local dealer . we have no clue

WERE I YOU I WOULD ASK THE HEATER COMPANY OR THE JANDY

I side the heat pump will be a small temp sensor mounted on the side of the inside area. Trace wire back and disconnect from control board. Replace the same way you removed the old one.

Check your salt level in pool. Also make sure that the wires going in to the cell are making good connection.

It keeps the clock time.if the power goes out.

Make sure you have the correct version pda and antenna. The new 18 function white/black pda will not interface with the old gray antenna. Likewise, the new black antenna will only interface with the white/black remote.

Internal bypass rarely goes bad. More likely the high limit switches have corrosion on them and have failed. Pull the high limit switches out and see if there is corrosion on them. If there is replace both high limits and put a dab or white lithium grease on top before installing.

One of your actuators more likely the suction side is bad or the toggle switch on the bottom or side of the actuator is in the off position.
