Tom, I had this problem earlier this year. First noticed that the stove would not light
. Then tried the fridge
and it would not light
. I suspected a blockage in the propane
line. First to eliminate the possibility that the propane
tank safety valve was not working correctly, tried using a different propane
tank, but no luck. Next checked whether the lines running FROM the regulator to the stove were blocked by disconnecting at the output side of the regulator and at the stove and then blowing air through. Determined that this was not blocked. I then replaced the regulator (amazon) even though it was only 2 years old. This fixed the problem.
I suspect the blockage was caused by impurities accumulated in an old propane tank passing into the regulator.
Based on my notes below, in hindsight would have been easier to simply replace the regulator.
Notes: To disconnect the propane lines at the stove and at the regulator, two wrenches must be used. Also, in the process of checking for blockage in the propane hose at the output side of the regulator, I broke the brass fitting on the end of the hose. The broken fitting appeared to have a very old crack in it (much of the cracked surface had oxidized). I found a replacement hose that was an exact match. Used LP sealant to put everything back together and leak tested everything. Also running an LP detector...
