Top-Down Heat: Troubleshooting and Replacing Grill Elements

⚠️ SAFETY FIRST: IMPORTANT

Grill elements are often exposed and susceptible to physical damage or grease splatter. Always isolate the appliance from the mains before touching or testing. Note that "infra-red" grill elements glow red during operation, while standard metal-sheathed elements may not—do not assume an element is faulty just because it doesn't glow.

In this post we will talk about grill elements, there are a few different variants but all work on the same principle of electricity running though the internal element and all can be easily be tested with a multimeter and most are easily replaced.

There are 2 types infra red or non infra red ones , the former glow red and heat the food with very strong direct heat.

This can cause some confusion as the ordinary one do not glow and look faulty. 

Isolate the cooker oven from any mains power before working on them.

To replace an element its usually just 2 screws and 2 wires unless there is  dual element in which there will be 4 wire connection sometimes this can be done internally without removing rear cover of the oven by pulling the wires through with the element and noting the wiring colour terminations.

Some grill elements are designed for easy removal and have an electrical connection inside the cavity to remove , some will be designed to unclip and drop down for cleaning while others are clipped up permanent and you need to undo the brackets or unclip from the brackets in order to remove them and other have no brackets whatsoever the rear mount takes the weight of the element and all you need to do is unscrew remove terminals and pull free but sometimes elements might be attached via the rear of the cooker oven making it necessary to strip the back covers off .

Taking a photo of the connections is always a good idea and take photos of any other parts of disassembly that you think might help you on rebuild.

To test an element you need to test for continuity of the element so you connect your multimeter leads one to each end of the element terminals and set meter to ohms or continuity mode and take the measurements. You can also test an element for its insulation resistance integrity you need to test from the element electrical terminals to the body of the element by inputting 500v the reading should be very high ohms, showing that no current is leaking from the element to the earthed casing of the element so no leakage to earth- which could cause tripping of the mains electricity supply see our post on this here.

The grill (or broiler) element is the high-wattage component at the very top of your oven. While they are built to be robust, they are common failure points due to the intense heat they generate.

Testing the Element

1. Continuity Test: Using a multimeter set to Ohms ($\Omega$), place a probe on each electrical terminal of the element. You should see a low resistance reading. An "OL" or infinite reading indicates the internal filament is broken.

2. Insulation Resistance: To check if the element is "leaking" current to earth (which trips your RCD), test between one of the electrical terminals and the element’s outer metal casing. This should ideally show a very high resistance (Mega-ohms).

3. Dual Elements: Some grills have two circuits (inner and outer). These will have four terminals. You must test both circuits independently for continuity.

Replacement Shortcuts

• The Internal Swap: Like fan elements, some grill elements can be replaced from inside the oven cavity. If you unscrew the mounting brackets, you may be able to gently pull the wires through the insulation. Crucial: Always take a photo of the wire colors before disconnecting.

• Brackets and Clips: Some grills are designed to unclip and "drop down" for easy cleaning of the oven roof. Others are permanently fixed with rear-mounted nuts that require removing the back panel of the cooker.
