Furnace won't go on when it's cold and windy
Check and tighten all the mounting screws for any electrical/electronic boards/processors....I'm a burner mechanic and had this problem with my own furnace!! , drove me crazy..untill I simply snugged up the mounting screws on the controller but, it happened to be an oil fired unit..but THAT did solve the problem..easy to try good luck!!!
When it's really cold it cycles more often creating more chance for failure during start up cycles..law od averages.." a little windy" shouldn't affect it especially since it's been working fine all this time..
