Honeywell TZ-4 HVAC controller; 4 zones hooked up with power up zone closure dampers ; 3 zones w/ 2 dampers; 1 zone w/ 1 damper. Worked fine for first couple of days as should have. Now will only work if all zones are calling for heat leaving all zone dampers in naturally open position. Transformer is 24 volt a/c 75va. Voltage at 26 volts to 27 volts regardless of load. When first zone satisfy's within seconds it goes into purge mode opening all dampers and shutting down the furnace. Will not allow furnace to operate again until all zones call for heat? Any ideas??

Execute following sequence to force cooktop reconfiguration (Be sure the good ESEC20 UIB is installed into the cooktop)
1-Put all rotary control to the first detent position clockwise (1 o'clock).
2-Put all rotary control to the first detent position counterclockwise (11 o'clock). The system should then reconfigure, showing walking dashes on the cooking zones displays.
3-Put all rotary controls to "Off" position. There should be no more error code and the cooktop is ready for operation. Frigidaire Range Stove Oven Surface Element Board 318329620Frigidaire Range Stove Oven Oven Control Board 318347100
There are 3 answers possible for your question:
1) your heater has a Thermolimiter without Hot Warning Light indicator connector and the job is dne by the electronics tht manage the zone. In this case the timer indicates that the hob is cold but obviously it is not. The fault is at the Electronics.
2) The Heater is a double Zone (with an inner ring and/or an oval side) in this case the part that it is failing to switch on is activated only in the sequential Inner ring-Outer ring. If the temp of 550C is reached the Thermolimiter does the cut of power cycling +/- 50C in order to avoid exceeding the 550C nominal.
3) Wrong Wiring if the heater was replaced. The harness could have been swapped around. Heaters could be Ceramaspeed or EGO that have inverted power and thermolimiter faston. Eika heaters are different too. but for this you need to see what is inside the hob and it is dangerous if you are not a qualified electrician.

the damper vent door from the freezer to the refrige located between the 2 sections has frozen shut and cannot open to let cold air into the refrige from the freezer,its behind a plastic grille near the top of the units divider you should be able to hear a fan in this area too its in there open this up and defrost with a hand held hair dryer if iced over,then make sure fan is operating,then move the temperature control and see if it opens up
You have to determine if the control or the burner is bad. Only way is to verify power from the control. If power is there the burner is bad. If the control is not powering the burner then the control is bad. Rarely is it both but not a impossibility. 240 volts so a trained professional is preferred. Eric
you have a zone valve and a tank stat that controls the temp of your hot water. when the water reaches the temp set of the tank stat the zone valve closes and stops water going to the tank. turn up the stat and see if the valve opens. you will hear a wherring noise. if not working you may have to change one or both of these but you can put the valve on manual by moving the lever in the side of it to then manual position till you get it fixed
