First check the batteries if the T-stat has batteries.

You then locate the fuse on the control board and see if it is blown. You will also want to check for 24V coming out of the transformer. If you do not have 24 V there, but you are getting high voltage TO the transformer, you need a new transformer.

You can check for voltage at the thermostat as well.

Miele 212 oven does not work. We have a Miele oven that does not work anymore. 220V gets to the oven and then nothing happens, no lights, no display, nothing... Advise anyone?


Nothing Works, or the Oven / Range / Stovetop Works Only At Certain Times:
1.Home breaker flipped or the fuse blown?Possibly an electrical surge has flipped the breaker. Check your breaker or fuse box and replace or reset as necessary.
2.Power cord plugged in?Grab the plug and wiggle to determine a good connection.
3.Power cord damage?Damaged rubber with wires showing through or the wire is being pinched can cause issues. Electrical tape is acceptable for covering damaged wires.
4.Aclicking sound could be something wrong with a relay. Check for any loose connections around the main control board on your oven. The click you hear is a relay losing power and switching back on. If the clock resets then something is causing power interruptions to the board.
5.
6.Even a bad relay door switch will hinder your oven from operating.

If your oven has internal fuses, a wiring or component problem could have caused a fuse to blow. A blown fuse is an indication that a component has shorted or failed, and the problem will need to be corrected. Most ovens that use fuses will have an indication of the circuits that are affected by a particular fuse. If an oven fuse has blown, then you should inspect the oven element and the associated wiring to determine the cause before replacing the fuse.

Dryer was working fine a load finished and when i started a new load it would not work meaning when i pushed the button nothing happened


Might be something as simple as the "settings" knob is not completely reset.... or the circuit breaker is open at the fuse panel... or the door latch sensor is not tight.

So, check each (in the order listed) and I suspect that you will correct the problem

Heat was working until 2 days ago. When i turn on heat nothing happens not even the fan turns on. I have a bryant cant find the model type. There is aslo a blinking red light


Hello
First check that the main circut breaker is not blown.
Next be sure you have gas or fuel oil going to the heater.

On some units there is a reset button located in the furnace control panel or a small low voltage fuse could be blown.

If a reset button is there push it in.Check your documentation as to what would cause this to happen.

After a power outage my T8011R display will not come on. Breaker is on and the auto fan works--so there is electricity to the thermostat. Is it fried or is there a reset or fuse that I need to address?


Hi, if the stat is working and running the fan, what has happened is the circuitry is faulty that shows the digital display. Before we are certain this has happened, check to see if the stat has batteries in it. Pull the front cover off and check. If it does, replace them and see if the display returns. If it does great! If not its the circuitry in the stat and will need to be replaced. Keep me posted.

A/C not turning on - Digital screen is blank


Your honeywell should have battery back up but the primary power for this is a 24 volt transformer located in the air handler probably in your attic. All these controls run on 24 volts
