    That Link is broken but it gave the message to go to propools.com. What am I looking for when I get there? Do I need to purchase a manual or something? I need a little more guidance if you will. Thanks, Darrell

    If you were sending towards a manual I did find a troubleshooting guide that said the pressure switch might be defective. There is only one and is there someway to bypass or test to insure it is defective before I buy one? Let me know, Darrell

  • Darrell Dobbs May 13, 2009

    I replaced the switch but that didn't resolve the issue. Still won't light the burners. Any other suggestions?

Pool heaters are exposed to the elements all year round, and it is common for the thermocouples to tarnish.
The thermocouple converts the pilot flame into energy and the regulator opens when it senses this miniscule amount of energy.
This is a safety feature so gas does not spew out of the regulator without a pilot to ignite it.
Clean the thermocouple with fine grit sandpaper, and adjust the pilot so just the tip of the flame is touching it.

Here are a few more troubleshooting guidelines for your pool heaters:

• The heater will not ignite.

If you are having a problem simply being able to ignite the heater and getting it to work properly, there are actually many things that you can do to try to remedy the problem.

One of the very first things you need to check in order to avoid spending a lot of unnecessary time is to make sure the switch is turned on. If it is turned on, you should move on and check the thermostat to make sure it is turned up to the desired temperature.

If this appears to be in working order, you then should check to make sure that the pump is running with a clean filter that has less than or equal to 16-psi on the pressure gauge. You may also want to check to make sure the gas valve is in the proper position and that the pilot light is lit.

You also should check that the plumbing and valves are all open and that the bypass has not only been installed, but also that it is properly adjusted. If you have checked on all of these things and still do not know what to do, you may want to contact a technician to take a look at the pool heater for you.

Thanks for using FixYa!!

Do you have 24V at the brown wire of the gas valve? If you do then it is probably a bad gas valve.
If you don't have 24V on the brown wire it is probably the ignitor.

Thank you for posting your question here on Fixya.com.


First you will need to get a hold of a digital or analog multimeter and set it for the lowest range of Ohms you can. Your safety circuit is a string of several switches all strung together in a row with the gas valve at the end and the beginning of said string. Any one switch being open or a bad connection anywhere in the circuit and the heater will not fire.

You task is to remove one end of the circuit from the valves TH or TT post and put one end of you meter on that wire and the other end on the TH/PP terminal. It will likely read infinite resistance. Leave one meter lead where it is and remove the other. Follow the circuit from the connected lead up to the first switch. Check continuity from the lead left connected to both sides of the switch. If there is continuity to both sides the switch is fine. Keep moving from switch to switch until you find the bad switch or connection. There may be more than one. When the circuit is working properly and there is nothing within the heater to cause it to shut off you should have 5 ohms or less across the entire circuit. Once you get the reading to that level the heater will work as it should

If you are not familiar with the process I described you would be better served hiring a pool technician to perform this repair as you can cause significant damage to the heater if you do not repair it properly.

Pentair Minimax CH Propane Millivolt Ignition Heaters error E05 what is it?


If you are firing, and then going off and getting an E05, your igniter is to blame. It may be glowing but it's getting weak. The diagnostic goes further but that is usually the fix.. With inactivity, the igniter is always to blame. You really need to fire it off weekly to make it reliable and make sure that your heater is serviced at least one time a year to keep all the internal components operating as designed.

Do not know how to start pilot light


There should be instructions on the inside of the heater access door. Make sure you are comfortable working with gas heaters. Make sure the shutoff valve supplying gas to the heater is on. Turn the gas valve to "pilot", press and hold it while attempting to light the pilot. Once the pilot is lit, continue holding the gas valve knob down for about 30 seconds. The pilot should stay lit once you release the knob. If the pilot stay lit, turn the gas valve to "on". Replace the heater access door and make sure you have proper water flow and attempt to light the heater. If it will not light, or the pilot will not stay on, you will probably have to replace the pilot generator. It provides voltage to run the heater and after time it wears out and produces less and less voltage. A millivolt heater runs on less than one volt so any power loss can be a problem. If you are able, test the pilot generator with a multimeter to see if you are getting at least 500mv when the pilot is on. If not, you should replace the pilot generator or even the entire pilot assembly. Hope this helps...
