Rangemaster E5 fault codewhat it means and how to fix it
Rangemaster publish two meanings for E5 in two different guides — an over-temperature in one, a mains voltage error in the other. Check which guide covers your model.

What E5 means
This is the code that requires you to know which Rangemaster document applies to your hob, because the company publish two answers and they are not variations on a theme. In the Eclipse 90 guide, E5 is given as the internal temperature of the hob being too high, and the published remedy is to switch off using the on/off control and let the heaters cool down. In the RMB60HPEIGL guide, E5 is given as a mains voltage error — mains voltage too low or too high — and the published route is to check the wiring and the supply, with the power unit replaced only if everything there proves correct.
One is a hot hob that needs to cool. The other is an electrical supply problem that has nothing to do with temperature. Acting on the wrong one wastes your time at best and sends an engineer after the wrong component at worst. So the first thing to do is find your guide number, which is printed on your user guide in the form U110602-06, and work out which table you are reading. If you cannot find the guide, the symptom usually separates them for you. An over-temperature code appears after sustained heavy use, typically on high power with several zones going, and it clears once things have cooled. A voltage code appears regardless of how long the hob has been on, often from cold, and cooling makes no difference to it.
If it happens on a cold hob, you are almost certainly looking at the supply. The over-temperature reading is worth understanding on its own terms, because it is not usually the hob failing. Induction electronics sit under the glass and are cooled by a fan drawing air through the appliance, and anything that restricts that airflow raises the internal temperature: an obstructed vent, a cooling fan that has failed, or an installation that did not leave the ventilation gaps the fitting instructions asked for. Rangemaster publish a separate code for a disabled cooling fan, which is the more specific version of the same problem.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Genuine over-temperature under the glass | Table A’s meaning. Sustained high-power cooking, particularly across several zones, raises the temperature of the electronics until the hob protects them by stopping. | Common |
| Restricted ventilation to the electronics | The usual reason an over-temperature appears sooner than it should. Blocked vents, or an installation without the ventilation gaps the fitting instructions specify. | Common |
| Mains voltage out of range | Table B’s meaning, and entirely separate. Rangemaster’s published route is to check the wiring and the supply before condemning anything in the hob. | Occasional |
| A wiring or connection fault at the appliance | Produces an out-of-range reading without anything being wrong with the supply itself. It sits with the connection rather than the hob. | Occasional |
| A failed power unit | Rangemaster place this last on the voltage side explicitly — the power unit is replaced only after the wiring and supply have been shown to be correct. | Occasional |
What to try yourself
Find your guide number, printed on the user guide in the form U110602-06. This is what tells you which of Rangemaster’s two tables applies.
If you cannot find it, note whether the code appeared on a hot hob or a cold one. Cold points at the supply reading; hot after heavy use points at over-temperature.
For the over-temperature reading, switch the hob off at its on/off control and let it cool down. That is Rangemaster’s own published remedy.
Check nothing is blocking ventilation around the appliance, including anything stored in the cupboard or drawer directly beneath it.
If it returns on a cold hob, treat it as a supply question rather than a hob fault and stop resetting it.
Call an electrician for the supply side, or an authorised service agent for the hob, and tell them which guide number you have.
Do not lift the glass or open the appliance. The induction electronics are mains powered and hold charge, and the glass is bonded rather than simply resting in the cut-out.
Get a qualified appliance engineer to look at your Rangemaster E5
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.

Nothing if it is an over-temperature that cools and clears. An electrician’s visit for a supply problem, and a power unit at the top of the range — which Rangemaster place last, after the wiring and supply have been checked.

Common questions about Rangemaster E5
How can one code mean two things?
Because Rangemaster wrote different tables for different platforms and different audiences. The Eclipse 90 guide carries an owner-facing table where E5 is an over-temperature; the RMB60HPEIGL guide carries a service-audience table where it is a mains voltage error. Both are their own published documents, which is why matching your guide number matters more here than on other brands.
It happens on a cold hob.
Then the over-temperature reading does not fit and you are almost certainly looking at the voltage meaning. Rangemaster’s route for that is to check the wiring and the supply first, and to replace the power unit only if both prove correct — so this is a question for an electrician before it is one for a hob engineer.
It only happens when I use several zones at once.
That fits the over-temperature reading well. Running several zones at high power puts the most heat into the electronics under the glass, and the hob stops to protect them. Let it cool as Rangemaster instruct, then check that ventilation around the appliance is not restricted — that is what usually makes it appear earlier than it should.
Can I keep using it?
On the over-temperature reading, yes, once it has cooled — that is the published remedy. On the voltage reading, no, not without finding out why the supply is out of range. A hob repeatedly seeing a voltage it does not expect is reporting something real about the circuit feeding it, and resetting past that is treating the messenger.
