If you are meaning a 'Hot Surface Ignitor' or 'HSI' the part will cost somewhere between $10 to $80 Dollars U.S.. The labor price for the replacement could be as low as $50 U.S. to over $500 U.S. The Price you pay for the ignitor from the service company could be well over $100 U.S. by the time they mark it up.

Then, how long does a hot surface ignitor last?
2 to 3 years
Furthermore, how much does it cost to have a furnace ignitor replace? The average cost of furnace ignitor replacement done by a professional is around $195. The price range for this affordable furnace repair is $30 to $245. If the repair is made during an emergency call, cost can rise to $300 or more.
Accordingly, how much does an ignitor cost?
Ignitor Replacement Cost An ignitor replacement costs $150 to $250 unless it happens in the middle of the night. After hours or emergency service fees can raise that to $300 to $500.
How do I know if my hot surface ignitor is bad?
Set the multimeter so it can properly measure a resistance of 10 to 200 ohms. Disconnect the hot surface ignitor from the control board and measure the resistance. A good hot surface ignitor will have a resistance of 40 to 90 ohms. Greater than 90 ohms indicates a failing or failed hot surface ignitor.
Related Question AnswersWhy do furnace ignitors fail?
Most of the time when ignitors go bad that often it is because the ignitor is not shutting off after the gas in the furnace is ignited. If the ignitor stays on for an extended period of time this will make the ignitor short-lived. Too much voltage to an 80 volt ignitor will burn them out quickly.Can you clean a hot surface igniter?
Clean the dust off the hot surface igniter by leaving the igniter in place and blowing air through a straw. This part breaks very easily; don't even touch it. In fact, when you replace the furnace doors, do so gently to avoid breaking the igniter.How does a hot surface ignitor work?
Hot surface ignition uses M-shaped silicon carbide igniters as an alternative to spark igniters. Since natural gas ignites at approximately 1,200F, any surface above that point will cause combustion. The igniter then shuts off, and a flame sensor detects combustion in less than 10 seconds or shuts down the gas valve.Where is the furnace ignitor?
Unscrew and remove the service panel on the side of the furnace and find the ignitor. It is usually mounted on a V-shaped bracket near the gas port. The ignitor has two wires attached to the back of it and has a flat metal tip.Do flame sensors go bad?
It's possible for a flame sensor to go bad; but more often than not, it is not broken, just dirty from carbon buildup. Because a flame sensor has a very low tolerance for variations in the reading it takes, the slightest coating of carbon can cause it to misread and shut down.How do you replace a thermocouple?
How to Replace a Water Heater's Thermocouple- Turn off the gas supply.
- Unfasten the three nuts that hold the thermocouple and the two gas tubes to the valve.
- Detach the thermocouple from the burner.
- Install the new one the same way that you removed the old one.
- Turn the gas back on and follow the lighting instructions on the water heater.
How many volts are sent to a furnace spark ignitor?
Troubleshooting a Hot Surface Ignitor (HSI) The igniter is located in the flow of gas entering the burners. When the thermostat calls for heat, 24 volts are sent to the electronic ignition control module, which energizes the furnace blower and other systems and sends 120 volts to the HSI.How long do blower motors last?
10 to 20 yearsWhat are hot surface igniters made of?
Hot Surface Igniter Configuration The two composition materials generally associated with hot surface igniters are silicon carbide and silicon nitride. Silicon carbide is a compound of carbon and silicon and is characterized by a low density and oxidation resistance.How many years does a gas furnace last?
15-30 yearsHow do I clean my furnace?
How to Clean a Gas Furnace- Turn off power/gas to the furnace. Turn off power to the furnace at the breaker box.
- Clean furnace surfaces. Wipe exterior surfaces with a damp rag.
- Remove the blower.
- Carefully clean the blower.
- Clean the pilot or hot surface igniter.
- Clean the flame sensor.
- Inspect the drive belt.
- Lubricate (but not too much).
What is an ignitor on a furnace?
The hot surface ignitor is a device used in most modern furnaces to ignite the gas you use for heat. It's a relatively simple component that works quite like a toaster in that its heat is generated by forcing 120 volts through an exposed, resistant material.Can I replace my own furnace?
Yes, furnaces do fall into the permit zone. In most states, a furnace or mechanic permit is a requirement by law for those who need to fully replace a furnace. Furnace replacement and installation is a major home project requiring a great deal of work by installation teams and contractors.How much does it cost to replace a thermocouple?
Thermocouple Replacement - $20-$150 Calling a professional plumber to install a new thermocouple should only be up to $150. If you do the work yourself, you will only pay the price of the part which is about $20.How much does it cost to fix heat in car?
Cost to fix a car heater Most heating-related repairs range from $300 to $1,000, he says, but it's difficult to pinpoint an exact number because of the variety of problems that exist. A decrease in the coolant level or a leak in the coolant system is one of the more common problems, Mattson says.How do you replace a thermocouple on a furnace?
Replacing a Thermocouple- Shut off the gas and electrical power to the furnace.
- Remove the furnace's access cover.
- If the furnace has been running, wait 30 minutes for the thermocouple to cool completely.
- Unscrew the nut that holds the thermocouple end fitting into the gas control valve, using an open-end wrench.
