Suburbun rv waterheater 10 gallon with electric ignitor makes clicking noise because it'strying to ignite but it's like no fuel is getting to it to start.

I had a similar problem, I could hear the valve clicking and spark working, but no flame. I checked for voltage as per the previous post, and checked continuity of both coils. Both showed voltage and continuity, but the ohm reading on one coil was less than the other.

I called a rv repair shop looking to buy a new valve ($120 - ouch). He didn't have one and when I explained what I had checked, he said could be that only one valve is opening. He suggested I remove one wire from each coil, turn the heater switch on and when I hear the spark igniter, touch a wire to one of the coils at a time. If it clicks, then it's fine, if it doesn't, then it could be the coil that needs replacing or the valve is stuck. If you see a spark as you touch the wire but no clicking, then it's a stuck valve. If there's no spark, then it's most likely a defective coil. A stuck valve can sometimes be freed by tapping with a screw driver.

In my case, one valve clicked, the other didn't and no spark was seen so I had a defective coil.

The previous poster is right, replacement coils are not offered as a replacement part - but - the repair shop I talked to saves all the coils out of old heaters and I was able to buy one from him for $10.

Problem solved, heater now works!!

Check your valve wire connections with a test lamp or volt meter to see if you have 12 VDC going to each solenoid when the unit is trying to light. Then check your valve coils for continuity.

Assuming the electrode is sparking, you are getting voltage to both solenoids, and you cannot smell LP gas when it is trying to light, you may have a bad coil on your gas valve.

You will have to buy a new gas valve as Sububran does not sell solenoids by themselves.
