Question about Viking 27" Professional Select Built-in Electric Single Wall Oven
The problem is with a Viking 30" single electric oven (VESO 105) purchased around 2003. It has dual cooling fans for the electronics. They come on at low speed for around 15 minutes during preheat. Then, a relay clicks and they change to a very high speed, making them very loud - too loud for comfort.
On turning off the oven and opening the door to speed cooling, they still run loudly at high speed for 30 minutes.
The fans have been inspected; the noise is not from bearings or a blade hitting an obstruction.
The fan tstat switches have been replaced and lifted slightly off the metal surface (to reduce contact). This did not solve the noise problem, and actually caused the fans to run longer (45 minutes) after oven shutoff.
Three different Viking tech support reps have given 3 different suggestions (replace the stats/fans; replace the wiring harness and control board; live with the problem, it is a design flaw in the model) but seem to just be guessing.
Has anyone else experienced this problem and actually found a fix? Many thanks in advance for any reply.
Its the control board fault as the components in the board are getting loose somewhere internally or not giving proper voltage required to the fan to make it run and due to that the fan is running in different speed as normal and turning off so the board needs to be checked and that faulty part should be located and replaced.as replacing whole control board is not much advisable as its just a fan problem so it will be a minute component replacement to make the unit proper.
