Chosen Solution
( right model Frigidaire BFEF374A ) I bought this used stove and the digits on the digital display are barely visible. I sought a solution and found that cleaning contacts or changing the capacitors might solve the issue. Contacts of the display are welded in the unit’s board but I changed the capacitors and it is still the same.
Possibly a cold solder joint on the control board. Reflow it it with a cheap soldering iron. That failing, replace it.
