Question about Heating & Cooling

1 Answer

I have a problem with an Armstrong SX90 gas furnace. model GUK100D14-2B serial number 8497G26541 The ignitor is not 'glowing' and therefore the pilot won't light. Everything seems to be sequencing okay...the blower starts and you can hear the gas valve click when the ignitor should glow but no glow....any ideas?

Buy a new ignitor either from the ignitor store online, or your local distributer, Contracter, dealer.. they usually run from 15 dollars to 35. Their simple to change out and deffinite do it yourselfer... Oh and turn off power at breaker panel, you don't need any unexpected surprises!!

Furnace wil, not ignite when calling for heat


For this answer, we need a model and serial number.
Generally, be sure the power is on, does the heat moving device run? (Fan for air, or pumps for water)

Whirlpool super capacity 465 will not heat properly is cooler than says


is it gas or electric and you should always send the model number off of the machine so we can help you better.if it's gas, you should be able to see the ignitor start to glow orange,when it does start to glow the ignitor should lite the flame within 40 seconds,if it doesn't then you have a bad ignitor,if you can't see it glowing remove the racks and take up the floor so you can see it.if you need more help send the model number,if it's a regular stove with the 4 burners on top open the bottom draw under the oven door,look on the frame and you'll see a tag with the model and serial number,just need the model number

I have a maytag gas stove model #MGR5775QDQ serial # 14863475CX the oven takes a long time to light and when it does it will not maintain a temp.


Hi,
You have a bad ignitor to your oven. Part number you should replace is 12400035. This should fix this problem. Just because it glows does not mean it work correctly, it works off of the flow of electricity rather then the glow of the ignitor.

Why heater coils glow?


It sounds like you're describing one of two things. The hot surface ignitor in a gas-fired furnace, or the resistive heat strips in an electric furnace.

The hot surface ignitor in a gas-fired furnace lights the burners. This ignitor in modern furnaces serves the same purpose as the standing pilot flame did in older furnaces. It provides the required heat to ignite the gas at the burners. Without an ignition source, a gas-fired furnace cannot provide heat. When the ignitor is activated it will glow bright orange or yellow.

The resistive heat strips in an electric furnace actually provide the heat to a home or building. When the furnace turns on, the heat strips are activated and usually glow orange when they reach peak temperature. In almost all cases, the heat strips are not easily seen or accessed without removing covers or panels inside the furnace.

Intertherm gas furnace


It appears your furnace is a downflow furnace. The sensor will be located near the bottom of the furnace. When you first turn it on, you should see a red glow.....this is the hot surface ignitor. Normally, the Hot Surface Ignitor is located on one end of the burners and the Flame Sensor is located on the oppoosite end of the Burners.

Furnace will not come on but thermostat is showing information


turn off power to furnace and open the front panel and see if you can see burners and gas valve and Hot surface ignitor.
If you can. turn furnace on and watch to see if the ignitor glows.
Let me know what you find. If it doesn't glow you probably have a faulty Hot surface ignitor.
If I had make and model number I should be able to find the part
