What Temperature Probe Error
actually means.

TQ3 conveyor toasters with the touchscreen control regulate heat through an RTD temperature probe. When the probe or its wiring fails, the screen shows Temperature Probe Error and the toaster cannot hold a consistent shade. The manual's checks are resistance and wiring tests, and its final fix is a new probe.

What to do when Temperature Probe Error shows on the commercial appliance

Before you book,
in this order.

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

01

Switch the toaster off and let it cool before touching the conveyor area.

02

Restart it once and watch whether the message returns during warmup.

03

If it does, stop using the toaster and book a visit for the probe and its connections.

Still there?

It usually turns into commercial controls and board repair. Book with the code and the model number.

What not to do

This message is not about heating elements; element trouble shows as Heating Error. It is also not an overheated control board, which has its own Control Board Overtemp message.

Questions
about Temperature Probe Error.

Can I clear Temperature Probe Error myself?
Switch the toaster off and let it cool before touching the conveyor area. If it comes back, it needs a visit.
Can I use a Hatco TQ3 that shows Temperature Probe Error?
Not reliably. Without the probe the control cannot keep toast color even, so book a visit.
What kind of probe does a Hatco Toast-Qwik use?
An RTD temperature probe, which the technician tests by measuring its resistance.
Why did Temperature Probe Error start after my TQ3 was moved?
A connection loosened in transit is a common cause. It still needs a technician to check the wiring.

Back to your everyday

Still showing Temperature Probe 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.
