The heating element of the heater is made up of alloy which has very high resistance so when current flows through the heating element, it becomes too hot and alows red. But the resistance of cord with is usually of copper of aluminium is very law so it does not glow.
The heating element of the heater is made up of an alloy which has very high resistance. So, when current flows through the heating element, it becomes too hot and glows red due to the heating effect of current. But the resistance of cord which is usually of copper or aluminium is very low so it does not glow.
If the element does heat slightly but it won't glow eventually across the element and it's not heating enough, it sounds like the element is just out of range. The ground wire wouldn't have anything to do with the dryer not heating properly.
This is a fairly simple test, but one that people often skip when testing a heating element. Turn the oven on at any temperature and then check to see if your elements are orange or red. If they aren't glowing, they aren't working. If they are glowing, they're sending heat into your oven.
It is because the temperature of heating element is around 1000°C whereas visible light is produced if the temperature rises above 1500°C.
Gas surface burners are often slow to light or will not light at all because the burner or burners are wet or dirty, the electrode is not seated properly or the burner head and cap are not matched up properly.
Your electric oven's heating element (also sometimes referred to as a baking element) powers your oven's heating. If your heating element is not glowing red when you attempt to heat your oven, this can be a sign that it needs to be replaced.
The easiest way to check this is to turn the heating element on and inspect the temperature of the air coming out of your heating system. If the air is insufficiently heated, very close to, or at room temperature, there is probably something wrong with the heating element.
As an estimate, most cooker elements should last for about 5 years. Of course, this is dependent on the health and overall quality of your oven; the better your oven, the longer its parts should last.

A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. Heat is generated by the passage of electric current through a resistor through a process known as Joule heating.
The cord of an electric heater is made of thick copper wire and has much lower resistance than its element. For the same current (I) flowing through the cord and the element, heat produced. Consequently, the element becomes very hot and glows whereas the cord does not become hot and as such does not glow.
The heating element will stop working. The sparking ceases after a few seconds. There may also be a "burning plastic" odor at this time. We recommend that you not use the oven if the bake or broil element fails.
If you have oven issues, it's worth investigating the heating element as a potential culprit, but a broken heating element doesn't always signal the end of your oven's life. Spotting the signs of a faulty element early allows you to fix the issue with a simple replacement, saving time and money.
The most common problem with oven elements is when the oven light and fan come on but the oven element won't heat up at all. This is the classic sign that the element needs replacing.
Replacing a broken element isn't too complicated, but it can be tricky working in such a small space. Before you begin, you'll need to turn the power off to your oven. Then, take out the old element by unscrewing it and detaching the wires running into it.
Possible problems include several failure points 1) no power to the appliance — check plugs, breakers, wiring. 2) bad control — setting control failure, thermostat failure. Call a repair person 3) presuming you might mean the oven or only one heating element- an open heating element or a faulty connector.
