Harman PB105 gives 5 blinks and just won't keep going

[Tedg]

I replaced vacuum switch and the esp. And runs for awhile then goes out. No pellets are in the burnpot when fkashing status. This lead me to belief it was the vacuum switch. Also can't shut off with minimum temp switch so I put took less switch on the vacuum switch to stop the pellet feed. This was done after I started having the issues

Might help to post the stove's year, make and model in the title and your signature

Might be the esp since the stove is lighting?

I did replace my pb105 is a 2008. I wonder why continues to not feed pellets?

Maybe new esp isn't working properly

I believe it's okay because it did same thing with old esp. Today I plan on cleaning hopper and testing vacuum switch tube

 

[Zeus]

ok sorry I couldn't help maybe some others will have ideas

Thanks watching it now to see if combustion motor shuts down

Well if the vac switch is not being closed because of no or little vacuum stove won't want to run. 2008 unit. How old- when was the door gaskets last checked for seal?

 

[Bioburner]

If the vac switch is not closing the stove won't want to run. 2008 unit so has the door gaskets been checked for proper seal? Leaking gaskets can throw off the vent gas temps too and there goes the esp thinking something wrong. A warming stove expands and a seal good enough at startup fails.
Welcome

Welcome! It sounds like potentiometer on the minimum temp dial needs to be replaced ... happens on the dials on the Harman pellet stoves too. Have you checked all your gaskets to ensure good seals? Hopper & door.

Edit: Bioburner, I started answering and daughter has a popcorn popper issue ... it's dead Posted and now realize we were thinking along the same lines
