Can a new LP regulator go bad?

Had a new regulator installed on my motorhome in July (2 months ago).
Now, when using the stove, for example, the flame on one burner starts out ok but within 20-30 seconds it dies down to nearly nothing.
BTW, I have an outdoor grill with a gas line off my main tank. That line to the grill is located before the regulator and the pressure is fine.
All appliances after the regulator are affected by this problem. The refer won't operate on gas nor will the two furnaces.
Is the fact that the burner flame starts out ok then dies down be an indicator?
Any thoughts? Can a new regulator go bad?
Thanks for any help.

  • I had it replaced as it was 13 years old. Nothing else was replaced other than new pieces of pipe and fittings.
    BTW, what do you mean by "pig tail"?
  • Why was the regulator replaced two months ago?
    What else was replaced?

    Honestly I would have a propane dealer take a look at your system.
  • Yes, it can go bad. It can also just need an adjustment. You can also have a pigtail connector between the tank and regulator that has gone bad.
