Mijn probleem
It was preventing my house from heating.
Mijn oplossing
Very well. I read other comments to similar problems, watched some videos and jumped right in.
Mijn advies
Be sure to have the operators manual troubleshooting guide, order your parts, get your tools and don't be afraid to get in there and do the work.
