Frequently Asked Questions for Lochinvar & A.O. Smith 100311038 Control Board 320788-703 Use the Fast setting for
How should I use an automated answer from a seller's help system?
Do not treat suggested steps as proof they have been completed. Look for qualifications or exceptions included in the wording.
What should I compare when the same seller offers a product through different channels?
Ask about unclear differences before placing the order. Do not assume a saved preference transfers between separate systems.
What should I check if I want to withdraw a cancellation request?
Ask about any change to price or expected completion timing. Check that an original order will not remain active alongside a replacement.
