Max-e-Therm SR400NA Control Troubles

Q: I have the Sta-Rite model number SR400NA for both pool and spa, for almost 7 years.  Lately, the unit has turned itself on when there is heavy rain or snow.  I reside in Las Vegas and have never had this problem before -- and this has happened twice this year.

 

I have made sure that our indoor remote to the pool and spa area is not inadvertently turning the system on.  I plan on ordering the display cover for the control panel from you -- to replace my damaged unit.  The technician has looked at the unit twice and feels the problem must be because my heater display cover needs replacement against the elements -- resulting in shorting/firing wires that turn on the gas unit automatically.

 

Does this sound like it will resolve my problem?  Or are more "evil" demons at work?  Thanks.

A: It is most likely the control panel itself. The panels have been redesigned and now come assembled with the plastic top of the heater so they are sealed better. so you may find the clear cover is not enough. If you still have issues you may want to try the part at the link below, I attached a picture of it to this email:

Purex Islander Heater Not Getting Hot Enough

Q: I have a 11.5 KW Islander Electric heater in my spa.  It has and seems to be losing its ability to heat.  I can not get the spa temp above 98 degrees.  I suspect I need a new element.  How do I check to see if that is my problem and to you have what I need.

Laars Lite 2 Pool Heater Leaking

Q: I have a Laars Lite 2 heater, LG175N-C, 175000BTU, which is leaking. I think it is the heat exchanger. Can this be repaired/soldered or will it need to be replaced? Is is easy to dis-assemble and assemble?

A: A leaking exchanger means a physical hole in the tube, these cannot be repaired. You will need to replace the exchanger. You can order it at the link below:

Heat Exchanger for Laars LG175N-C

They are not difficult to put in, mostly just nuts and bolts. The first one I did took about 45 minutes. If you have a hole in your exchanger there is often a chemical problem in the water. If you would like to discuss any chemistry troubles you are having let me know, and we most likely can help you straighten them out.

Raypal Versa Pool Heater Not Working

Q: My Raypak Versa plus 151,000 BTU Nat. gas heater will not start when I turn it on.  The pilot is lit but I get nothing.  Help!!

A: The very first thing you want to check is the output voltage from the pilot generator. The two wires coming up from it should read 500 mV or .5 Volts DC. If you do not have at least 500 mV DC then you need to remove the pilot assembly and clean it very well. If you still do not get 500 mV after cleaning then you will want to replace the thermocouple.

Let me know what you find and we can work from there.

Main Burner for Comfort Zone Heater

Q: I am searching for the main burner with pilot bracket for a Comfort Zone spa and pool heater.  The model number of my system is PSG 355 – HT-P.  It’s a natural gas 355K BTU pool and spa heater.  This part is on the burner tray.  Can you please let me know if you carry this item, and if so, what the cost is? - Thanks

A: I am sorry but we can no longer get those burners. You may have to consider replacing your heater.

A small positive is that if you get a high efficiency pool and spa heater you will save a considerable amount on your heating bill. This heater is the most efficient one for pools and spas available at a reasonable price:
