Second opinion] I have a hi300 air heater that won't fire. I checked and cleaned the entire fuel system including replacing the fuel pump. It has good spark at the igniter. The fan kicks in and runs until it times out. I'm not sure what I should check next. Suggestions?

My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

I see you asked for a second opinion on this. I can't see the original question since I grabbed this so I will ask for a few things to see if they were checked.

Did you check the safety switch on this already? This is the time of year they go bad. You already mentioned you changed the pump so I am presuming it primed and is ready to flow fuel. Air can cause issues, but it will time out if no fuel before you get spark. Start at the witch first and see if it faulted on you and get back?

Did you still need assistance with this?

Do you need more time to resolve the issue?
