Furnace Not Starting? 5 Checks Before You Call
The five checks that solve a third of no-heat calls before a van rolls: thermostat batteries, breaker, furnace switch, filter and the error-code blink pattern.

HOOK (0:00-0:10): Standing at a cold register in Burnaby — before you call anyone, five checks, in this order. STEP 1 (0:10-0:30): Thermostat — confirm HEAT mode, raise the setpoint three degrees above room temperature, and swap in fresh batteries on any thermostat older than a year. STEP 2 (0:30-0:50): The breaker panel — find the furnace breaker, flip fully off, count to five, back on. A half-tripped breaker looks on and is not. STEP 3 (0:50-1:10): The light switch on the furnace itself — the single most-common no-heat cause in Metro Vancouver. Someone flips it thinking it is a laundry light. STEP 4 (1:10-1:30): Pull the filter and hold it to a lamp. A filter you cannot see light through is starving the unit — leave it out for the test and see if the furnace runs. STEP 5 (1:30-1:50): Count the control-board blink pattern and read it against the sticker inside the door. CLOSE (1:50-2:10): Still dead after all five? That is a real diagnostic — call us and tell the dispatcher the blink count; the right parts get preloaded before the van leaves. Comment which check fixed yours.
