Tech system in my twin-home for bat and kitchen exhaust.

Customer Question
Tech system in my...

Tech system in my twin-home for bat and kitchen exhaust. Recently the "20 minute" touch switches quit working. I can still run the system, but have to use the manual switch in the utility room.

Contractor's Assistant: I'll do all I can to help. How long have you been dealing with this?

3 weeks

Contractor's Assistant: Do you plan on doing the work yourself?

No. I have an HVAC service here now doing 6-month service on my furnace.

Contractor's Assistant: Are you an HVAC professional?

No, far from it - lol

Contractor's Assistant: Anything else we should know to help you best?

3 switches: 1 in each bathroom and one in the utility room (within attached garage).

None of the 3 one-touch switches works
HVAC Technician: Gaztech, HVAC Technician replied 10 months ago

Then I would look at the main connection at the control board in main unit. allthe timer go to the same terminals.

it may be a loose connection. also inspect control board itself for damage. burnt fuse if there is one.

If all is good then replace control board
