I use the range at my cottage (LP) and when the burners are lit the flame is norma,l but every 20 seconds or so, the flame drops down for a split second and then goes back to normal. Does the same if one burner is lit or all four are lit.
I thought it might be the regulator on the propane tanks and replaced that but the problem persists. This regulator had a leak at the knob for switching over to a new tank, thats why I replaced it.
You change out all the orfices & regulator in the unit to LP?
Yes it was converted to LP.
Have had the range for 7 years and it started doing this about a year ago.
Sounds like a gas supply issue or a regulator fouling out possibly. Check your supply pressure make sure it’s constant and good psi. Any problems with the oven operation? Remove the top and see the burn tube and see if the flames do the same thing during the bake mode.
Definitely a gas supply issue..you should probably check the pipes.
Sorry it took so long to reply.
Checked the lines and all appears ok. No kinks, bends or leaks.
Do I assume it is the regulator acting up?
