Hello,

 

around the flame box area you will see these-

 

there is a tiny reset button in the center. Press the button to see if it clicks.

 

Warning though...quite often a popped reset is sign of a bad exchanger and should be looked at by a professional

I see a switch like you say but ther is no reset button in the middle, my unit is probably around 15 years old.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 7 years ago

 

Do you have a model number? If it is a "roll out" it will have a button.

 

If it is a blower or limit switch it will not. The blower or limit will be on the front wall....the rollouts are specifically at the sides or top of the flame area

It was the heat exchanger that was cracked!!!
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 7 years ago

 

I see heat exchanger crack = tripped rollout.

 

I wish you luck and hope all goes well.
