Question about Raypak Rp2100 Pool & Spa Heater Lonox 407k Btu Natural Gas Polymer Header Digital Rp407aenc

1 Answer

We haven't used the heater for about a month. When I tried to fire it up tonight I got a message on the panel that indicated that it needed service to clean a filter. Then it attempted to light, but even though I could smell gas and hear the ignitor it did not light.

This tells me that the pressure switch is not activating. It either means that the pump is not moving enough water through the heater, or the due to the heater sitting without use, the pressure switch is clogged or failed. Easy part to switch , cheap to buy. E-mail me if you need help.

You have a bad heater core it needs to be replaced soon, your system cannot maintain pressure and you will have massive issues and failures due to this and you will have to replace alot more than just your heater core. I hope this helps you

I have exactly the same problem, light effect just went out tonight. Trying to work out if it is the motor or that little tiny cream box fixed to the terminals inside. If I take it out the lights come on. Just about to see if the motor is working, just that box that has gone.

Runs for about 15 minutes then shuts off .


I believe the pump setting is 6.0 for the 155 BTU model. I will know more after tonight, we are using a Reddy Heater 155 unit tonight at church. I will look on the side panel and see what the PSI should be for the pump pressure and respond either tonight or tomorrow.
