Open Question

Raypak RP2100 Pool Heater stared up and some leaves burned off but then it shuts off in less than 5 minutes and starts clicking trying to restart. Any idea's what could be wrong?

New gas line was put in and line was bled. Could it be line wasn't bled enough or thermostat is bad?

I had a similar problem and believe it or not it was the CAT. An easy way to test for this is to remove the O2 sensor right in front of the CAT. Once you removed it, plug it back in while unscrewed from the exhaust pipe and start up the truck. If it runs fine, the CAT is your problem. This is just a guess and it would be an easy and very cheap($0) test. You did not say if the truck was diesel or gas. Mine is gas that was exhibiting the same problem as yours...good luck!

SOURCE: running hot 1996 cavalier

please try a simple test for me. no.1: remove the radiator cap off the radiator. no.2: if you could see the see the radiator opening from within you car much better, then try to crank your car to an idle. if coolant blows out of the mouth of the radiator like an erupting volacano, then take note of this. no.3: while the engine is running at idle try to look at the coolant through the mouth of the radiator, if you see bubbles like washing your hands with soap and the suds trailing to a drain, then take note of this.

the reason why i'm telling you all of this is that, the coolant should flow like a clear stream. you don't have to worry about purging the system of air because, the water pump is already situated a few inches below the highest water capacity of the radiator. it means that if you drained your system and refiled the radiator to the brim, just start your engine and add a few more coolant to fill it up because the running engine simply purges the waterpump of air.

now, if you tried no.2, and you did see and somewhat like an errupting volcano, that means your engine is in serious trouble, so is no.3. however, a tolerable bubble flow is still possible but your valve clearances should be tuned if this happens. excessive bubbles accompanied by blow out of coolant means your combustion gases are seeping through the head gasket due to a damaged head gasket, warped cyclinder head, cracked cylinder head, or even a cracked cyclinder liner(or bore where the piston glides up and down). think back! did you ever experienced overheating you car to a point where it stalled completely? then, you need a thourough engine checkup.

SOURCE: car wont start

I think you have a bad fuseable link. Also,
I suspect your alternator is not charging your battery.

You have power with the new one, and it ran for the 20 minutes on your old battery. There also may be a
starter relay unit under the hood.

SOURCE: 1 year old hayward h1001d pool heater clicking

Actually, the clicking is likely causing the shaking. Inside the manifold of a H100 is a stainless steel diverter plate that send some of the passing water into the heat exchanger and lets the rest past and back to the pool. When it breaks, you will hear a 'clicking' noise at it rattles in the water path. When it breaks, the flow to the heat exchanger is intermittent and you will begin to boil the water, causing the shaking. This situation is dangerous, especially without a pressure relief in the heater or pipe. As long as your water chemistry is sound, Hayward will usually cover this under warranty even if the unit is over a year old. Contact them to get a factory authorized repair rep out at:

Raypack 2100 pool heater runs for a couple of minutes then loud banging noise. heater shuts off and error code HL appears

That HL is your high limit shutting the heater down. The banging is the sound of water boiling in the heat exchanger because it is moving too slow. This is almost always the result of the bypass or governor (thermostat) not working properly, so too much water is bypassing the heater. It's not too hard of a fix.

New thermostat and pilot/ burner assembly, but the flames from the burner fluctuate up and down then finally shuts off What could it be?

You replaced the gas control valve thermostat, and the burner assembly.
You bled air out of gas line.
Assuming the gas control valve is functioning correctly, the last things would be gas pressure, air intake, and vent draft. If gas control valve is electronic, check outlet with circuit analyzer and make sure ground is connected.
Also if water heater is located in hot attic, or tight house, these things can cause water heater not to function.

Whilpool hot water will not light

Unknown if this is new heater, or heater that worked before.

1) New heater: more information is needed about installation, type of gas valve, and what you have tried so far.

2) Heater that stopped working:
Manual is good start point, and then add a comment with which type of heater you have and what you have tried so far:
Problem can be simple or complex: dirty combustion parts and tubes; thermocouple is bad if gas control valve is not-electronic type; bad gas control valve thermostat; overheating tripped ECO because of bad thermostat or dirty burner parts; lockout due to FV event and exposure to flammable vapors; air in gas line need to be bled off; overly hot environment needs better ventilation; bad air supply because air intake needs cleaning; bad venting or downdraft or tight house needs ventilation; deteriorated burner parts need replacement because of moisture leak or exposure to chemicals; etc.

I have a SureFire Grill (SF30HOLP) that I recently converted to NG. For some reason the gas will flow through the regular and light, but at times I am not getting gas through the regulator. I have a...

I would try replacing the regulator, not very expensive and easy to do, first. If that doesn't fix the problem, call the gas company and see if there is a flow problem to the line itself. I have worked on grills that were operating properly, but there just wasn't enough gas flow in the line for the grill.
