What to do if my Raypak Electric Heater does nothing when the thermostat is on?
- AAnthony SandersAug 9, 2025
If your Raypak Electric Heater isn't working when you turn on the thermostat, it could be due to low flow, a high limit issue, or the thermostat not calling for heat. First, check the filter, skimmer basket, and pump. If you're using a 2-speed pump, switch it to high speed. Then, press and hold the knob for 5 seconds to ensure the flow rate displayed on the screen is at least 15 gpm (57 lpm). Finally, push the reset button and turn the thermostat to a higher temperature.
