Arrived and customer explained furnace would trip o he rollout safety. After running tests initially diagnosed failed rollout. When I repaired, furnace still had same issues. Dug further into furnace and all checked out ok. Narrowed issues down to either inducer motor or a heat exchanger issue. This cost of these repairs are a large investment for a furnace of this age. Spoke with customer looking at replacement furnace to avoid any further issues. Chris will be meeting with you Monday at 10 AM to go through replacement options.
