What Heating Error
actually means.

The TQ3 control compares the heat it asks for with what it gets. When an element or its relay connection fails, the screen shows Heating Error. The manual's checks are wire connections on the relay and element and element resistance, and its corrective action is a new heating element.

What to do when Heating Error shows on the commercial appliance

Before you book,
in this order.

Each step comes from Hatco's own guidance for Heating Error on its commercial appliances. Follow it to the end: the last card says whether this is a visit.

01

Look at the toast coming out: one pale side or a pale strip across the product helps the technician find the element.

02

Power the toaster down and up one time and watch for the message.

03

Book a visit if it does; element and relay tests are done with the power disconnected and the covers off.

Still there?

It usually turns into reach-in and prep table repair. Book with the code and the model number.

What not to do

Heating Error is not a probe problem; that is Temperature Probe Error. It is also not an overheated board, which has its own message.

Questions
about Heating Error.

Can I clear Heating Error myself?
Look at the toast coming out: one pale side or a pale strip across the product helps the technician find the element. If it comes back, it needs a visit.
Why is my Hatco toast pale on one side after Heating Error?
One element above or below the belt is likely out. The pattern on the toast tells the technician which one.
Can I keep using a Hatco TQ3 with Heating Error?
You can toast slowly if the rest heats, but results will be uneven. Book a visit before the rush.
Is a Hatco toaster element an owner-replaceable part?
No. It is replaced with the power disconnected and panels removed, which is a technician job.

Back to your everyday

Still showing Heating Error?

A booking with a code goes further when it has the code as shown, the model and serial from the data plate, and a word on whether the unit still holds temperature, heats, rinses or spins. With those three, the office can match the likely part to your unit the same day.
