What causes a furnace pressure switch to fail?
Check for a clogged hose port or cracked hose running from the draft inducer motor or condensate collector box to the pressure switch. These problems can cause the switch to trip or fail.
Can a furnace run without a pressure switch?
Without a properly functioning pressure switch, a furnace can’t function at all. A pressure switch is a safety feature that is designed to automatically shut the furnace off if it senses negative motor pressure. If the draft inducer introduces exhaust fumes back into the system, this can lead to backdrafting.
Is a furnace pressure switch normally open?
The pressure switch is a normally open switch that closes upon the manufacturer’s specifications for required negative pressure. If the inducer turns on and is working normally, the furnace pressure switch should activate. There’s no time lag on this either. The inducer motor creates this draft quickly.
How much does it cost to replace a pressure switch on a furnace?
Your furnace has multiple safety switches, but furnace pressure switches are more likely to fail than many switches. Even then, furnace pressure switches can have a life expectancy of at least 10 years. A furnace pressure switch replacement typically costs around $250.
How long should a pressure switch last?
