I bought a new thermostat and heater and replaced them both.
The heater was quite easy, the thermostat had a very long lead wire. I ended up cutting the existing thermostat wire and splicing and wire nut the thermostats in. Now, my freezer is not running.
The light bulb is on and so far the fridge seems ok.
What did I do wrong or what can I do now?
the freezer eventually kicked on - guess I replaced the thermostat alright. Now, if the coils still freeze up I will replace the mother boardthe freezer eventually kicked on - guess I replaced the thermostat alright.

you could try thermostat - search google eg. <https://www.espares.co.uk/search/ma856pt1727/fridges-and-freezers/thermostats/bosch>. could be your local repair shop has one for you. locally we have appliances in scrap yards and i have bought stuff for $2. if you do replacement, be very careful. unplug your unit and use a flashlight.
Sounds like a defrost problem. Is there frost build up on inside back wall of freezer? If heater is good, the control or the defrost thermostat may be bad. Is fan in freezer and fan at compressor running?
what ever u do make sure to turn off furnace power supply as u may well burn your furnace circuit board if you havent already. btw there is a fuse you may have to replace on the circuit board. now as far as wiring, its quite easy, look on your new thermostat, it has all the same lettrers.
w= white, r+red, g+green,c= common, b=blue blk=black, or=orange
then turn on furnace power, if nothing comes on look on the circuit board to repplace fuse, usualy 3 amps
have u checke the defrost heaters in the frezzer. also the termnation switch with the heaters.. if they dont work then it dont defrost and it builds up ice and wont work properly. ok
Check freezer fan is working.If ice formed over freezer fan by working. It's a common problem due to irregular defrosting. Keep freezer setting temp at 5 degree. And check defrost timer, thermostat,heater are working properly. Turn timer with small tip screw driver to shut off fridge. If not shut off, replace timer. Turn counter clockwise defrost thermostat. If fridge not shuts off replace defrost thermostat.Check heater by join the 2 wires in the defrost thermostat. And after 1 minute, unplug power and keep your arm on heater. If it's warm heater is o.k. Otherwise, replace heater. Once heater starts work at regular interval controlled by thermostat and timer, defrost will be good and effective cooling will also be in fridge compartment.
You have an automatic defrost problem. The refrigerator is not defrosting
Three important parts. It probably is one of these.
Defrost Timer
Defrost thermostat
defrost heater.
The fan is probably fine, but has nothing to do with Defrost
Check the heater continuity and change the heater defrost thermostat
then replace timer if those don't solve it.

If you can locate the defrost timer and advance it to the defrost cycle you should be able to see the defrost elements glow behind the rear panel in the freezer. Do this before the freezer gets too frosted up. If you can't see the glow then there is a problem with the defrost heaters or the defrost thermostat. Unplug the frig and remove all the racks in the freezer. Remove the screws holding the rear panel on. Locate the two heaters and check the resistance. IF open, replace heaters. IF ok check resistance of the defrost thermostat. IF open when cold, replace defrost thermostat.
If replacing heaters always replace defrost thermostat at the same time. It will save you doing so at a later date
Morning, This seems quite a easy problem to fix.! Check to see if the f/.freezer has to compressors (motors)? If so the you find that is more than likely to be that the fridge thermostat has broken. A very easy way of checking if you electrially minded is to remove the thermostat from the housing a connect the live and common wires together and switch on, It then should switch on if there is no other problems, Then just replace the stat.
Good luck......
Check for frost build up behind back panel. Defrost system consist of defrost timer or adaptive control board, defrost heater, defrost thermostat. check them here
