The best replacement is a good flowing computer fan....new or used.
The "used" can be had for almost nothing and they last longer than the factory TV fan.......check computer repair shops,they will have a large pile of good used fans of all sizes.

My sharp R409Y*A microwave overheats after 4 min every time and shuts itself off for a few min. It will turn itself back on, but if I use it right away, it will shut itself off again quicker.


I would say your cooling ran is not running, or your vent holes are blocked, or (if equipped) a filter is blocked.

Without the cooling fan, the magnetron overheats and its TCO (thermostat) shuts down all power to the oven until it cools back down to a safe temperature, then power is restored.

Jenn-Air Maytag double wall oven makes loud buzzing noise


There is a cooling fan for upper and lower oven they run at the same time no matter which oven in use it is fed from the oven manager no way to trouble shoot without pulling oven out some models use same fan for both so you could have a blower on hand remove back panels to access fans take a lead off fan to determine which one noisey

Need to know why a 97 mercury cougar won't start until cooling fan and fuel pump stop running


I would think it's a problem with (CCRM) constant control relay module . This module has relay's inside that control the fuel pump , cooling fans , A/C compressor clutch , PCM - engine computer power relay . And thier are electronics involved , solid state circuity . Google CCRM

Over heat cooling fan load noise remove and replace


A bearing more than likely has went bad causing your fan to stop properly cooling your unit. Replace with a compatible fan and you should be all set. Hope this helps.

My oven turns off on me after only a minute never heating up fully


Could be caused by either of following;

1. Faulty thermostat.
2. Faulty thermal cut out switch. (controls power to cooling fan).
3. Faulty cooling fan (not fan inside oven).

Test thermostat by setting thermostat to low temperature like 60 oC. If oven gets much hotter then its a faulty thermostat.
To test cooling fan and thermal switch take oven out and remove top or rear panels to expose components.
When oven gets hot the cooling fan should turn on. If it doesn't then check to see if there is a mains voltage present.
If mains current exist but fan is not turning then replace fan. If mains voltage is not present then its the thermal switch.
