My model bunn grx-b stopped working. Checked continuity on tank, fuse on tank, bottom switch, can top switch be at fauLt? If so how do I remove it?

Bunn switches if the rocker style as the looks like will have two leaves on the side of the switch that will need to be squeezed in order to get it past the square hole. These can be really tight but if your sure it's at fault then just crush it to remove the pieces. The new on should snap in if the hole was not damaged.
* Since your checking the brewer you should get the manual that may be available from (I haven't checked for this model but they usually post the manuals)
* This seems to be a home version of a VPR commercial brewer (but nicer). So expect the same parts for the fuse, thermal fuse, thermal disk (or thermostat).
* Note: If your not familiar with Bunn brewers then make sure you look at every piece of wire as some high limit fuses are inside plastic tubing or heater braiding.
* Thermal disks look like a metal button with a ceramic cap or button attached to it. This can be a high limit (reset-able) or a thermostat. * It may have a standard thermostat with bulb but it may be a thermsistor probe with a PC board to control the brew heat.
* Final; this is the 3d question on this particular brewer. All have similar problems with heating. It's the same with VPR's. If I set them up I know it works properly. It's when someone moves them to another office that's the problem as they dump out the water prior to the move then plug it in without refilling the tank. Thermal fuse blows. There is a link below showing how to set up this brewer.

Tank not heating

Could be one of several issues. MC won't hear if it has low water. Low water may be caused by scaled probe, no water supply or other flow problem. Could be that thermal fuses on element have blown and need replacing. Could be that heating element is burnt out. You will need to do some further basic diagnostics.

Is there a current recall on Bunn model GRX-B?

Don't know about a recall, but the most common cause is a bad element.

No power getting to Bunn coffee maker

Okay, When going away most people empty the tank completely. When returning you must start it as if brand new out of the box. Follow the MFR's instructions for an initial fill and heating.
Some don't empty but just unplug just as you did. Places like Arizona with very low humidity can dry out or lower the tank water where the heating element is not in water. This element will overheat and trip out the thermal fuse.
**Another scenario is the empty unit was plugged in and heating while someone was going to get the water. Over heat then blows fuse.
** The "Vacation" switch is very visible so you probably have tried it already and you have already checked the outlet and breakers. Still looks like a thermal fuse problem.
** Switches do go bad as they are turned on and off daily. Possible yours was bad before but never noticed as it was never turned off till on vacation.
** There are other possible scenarios but all point to a thermal fuse, thermal limit, blown fuse, switch, Heater element, or cut wire (Mice). All are electrical problems and require a MFR tech. Contact your vendor or MFR for service.
