You need to clarify what type of furnace, oil, gas, If the furnace is 8 years old like you said then the heat exchanger will be under warranty, if he replaces it ask to see the crack.

it also could be that the service man installed the wrong or possibly plugged nozzle if this is an oil fired furnace. there is a cad cell that will shut down the burner if it doesn't see a good enough flame.you can push the red button(reset) ONCE if no flame then get a qualified service tech to look at it.

Thank you for advice. I will keep eye on it. It happened a couple of times so far. I had a tech visiting me and he said that we need a new furnace but is is only 8 years old.

the only thing that would require a new furnace on an oil system is a cracked heat exchanger. a qualified tech has many ways to verify the integrity of the exchanger. without a crack i will never tell someone they NEED a new furnace, now replacing one for a higher effeciancy model is a new story

if tis a furnace not a boiler, and the little button you refer to happens to be a roll out switch you need to call a service man you could have a serious & dangerous problem

I am a little confused when you say you had a filter changed on a boiler. As for the red button if you notice there is a dial behind it with temps on it I assume the temp is set to low you can go as high as 220 as it is under pressure it won't boil at this temp. That button is your high limit switch.

poor air flow through a furnace and poor air distribution to the occupied space can result in overheating of the heating exchanger. this can result in the opening of system limit switctes that will de-energize the system.Check: air filters,blower motor,blower wheel,belts and pulleys if applicable,return grill, supply reisters,loose duct lining. what yur looking for is reduce air flow.
